The fields, "toc" and "cd_info", of "struct gdrom_unit gd" are allocated
in "probe_gdrom()". Prevent a memory leak by making sure "gd.cd_info" is
deallocated in the "remove_gdrom()" function.
Also prevent double free of the field "gd.toc" by moving it from the
module's exit function to "remove_gdrom()". This is because, in
"probe_gdrom()", the function makes sure to deallocate "gd.toc" in case
of any errors, so the exit function invoked later would again free
"gd.toc".
The patch also maintains consistency by deallocating the above mentioned
fields in "remove_gdrom()" along with another memory allocated field
"gd.disk".

This reverts commit 093c48213ee37c3c3ff1cf5ac1aa2a9d8bc66017.
Because of recent interactions with developers from @umn.edu, all
commits from them have been recently re-reviewed to ensure if they were
correct or not.
Upon review, this commit was found to be incorrect for the reasons
below, so it must be reverted. It will be fixed up "correctly" in a
later kernel change.
Because of this, all submissions from this group must be reverted from
the kernel tree and will need to be re-reviewed again to determine if
they actually are a valid fix. Until that work is complete, remove this
change to ensure that no problems are being introduced into the
codebase.

The function qlcnic_dl_lb_test() currently calls netdev_alloc_skb()
without checking afterwards that the allocation succeeded. Fix this by
checking if the skb is NULL and returning an error in such a case.
Breaking out of the loop if the skb is NULL is not correct as no error
would be reported to the caller and no message would be printed for the
user.

niu_pci_eeprom_read() may fail, so add checks to its return value and
propagate the error up the callstack.
An examination of the callstack up to niu_pci_eeprom_read shows that:
niu_pci_eeprom_read() // returns int
niu_pci_vpd_scan_props() // returns int
niu_pci_vpd_fetch() // returns *void*
niu_get_invariants() // returns int
since niu_pci_vpd_fetch() returns void which breaks the bubbling up,
change its return type to int so that error is propagated upwards.

Upon review, this commit was found to be incorrect for the reasons

The change here was incorrect. While it is nice to check if
niu_pci_eeprom_read() succeeded or not when using the data, any error
that might have happened was not propagated upwards properly, causing
the kernel to assume that these reads were successful, which results in
invalid data in the buffer that was to contain the successfully read
data.

The condition of dev == NULL is impossible in caif_xmit(), hence it is
for the removal.
Explanation:
The static caif_xmit() is only called upon via a function pointer
`ndo_start_xmit` defined in include/linux/netdevice.h:
```
struct net_device_ops {
...
netdev_tx_t (*ndo_start_xmit)(struct sk_buff *skb, struct net_device *dev);
...
}
```
The exhausive list of call points are:
```
drivers/net/ethernet/qualcomm/rmnet/rmnet_map_command.c
dev->netdev_ops->ndo_start_xmit(skb, dev);
^ ^
drivers/infiniband/ulp/opa_vnic/opa_vnic_netdev.c
struct opa_vnic_adapter *adapter = opa_vnic_priv(netdev);
^ ^
return adapter->rn_ops->ndo_start_xmit(skb, netdev); // adapter would crash first
^ ^
drivers/usb/gadget/function/f_ncm.c
ncm->netdev->netdev_ops->ndo_start_xmit(NULL, ncm->netdev);
^ ^
include/linux/netdevice.h
static inline netdev_tx_t __netdev_start_xmit(...
{
return ops->ndo_start_xmit(skb, dev);
^
}
const struct net_device_ops *ops = dev->netdev_ops;
^
rc = __netdev_start_xmit(ops, skb, dev, more);
^
```
In each of the enumerated scenarios, it is impossible for the NULL-valued dev to
reach the caif_xmit() without crashing the kernel earlier, therefore `BUG_ON(dev ==
NULL)` is rather useless, hence the removal.

The macro "spi_register_driver" invokes the function
"__spi_register_driver()" which has a return type of int and can fail,
returning a negative value in such a case. This is currently ignored and
the init() function yields success even if the spi driver failed to
register.
Fix this by collecting the return value of "__spi_register_driver()" and
also unregister the uart driver in case of failure.

of pci_request_mem_regions"
This reverts commit 9fcddaf2e28d779cb946d23838ba6d50f299aa80 as it was
submitted under a fake name and we can not knowingly accept anonymous
contributions to the repository.
This commit was part of a submission "test" to the Linux kernel
community by some "researchers" at umn.edu. As outlined at:
https://www-users.cs.umn.edu/%7Ekjlu/papers/full-disclosure.pdf
it was done so as an attempt to submit a known-buggy patch to see if it
could get by our review. However, the submission turned out to actually
be correct, and not have a bug in it as the author did not understand
how the PCI driver model works at all, and so the submission was
accepted.
As this change is of useless consequence, there is no loss of
functionality in reverting it.

The original patch was authored by a member of the Underhanded

hardware anymore so I can't test this, but it seems like a pretty

Screen flickers rapidly when two 4K 60Hz monitors are in use. This issue
doesn't happen when one monitor is 4K 60Hz (pixelclock 594MHz) and
another one is 4K 30Hz (pixelclock 297MHz).
The issue is gone after setting "power_dpm_force_performance_level" to

sclk is too low.
So resolve the issue by disabling sclk switching when there are two

Currently, the code fails because flexible array _levels_ in
struct SISLANDS_SMC_SWSTATE doesn't allow for code that accesses
the first element of initialState.levels and ACPIState.levels
arrays:
drivers/gpu/drm/amd/pm/powerplay/si_dpm.c:
4820: table->initialState.levels[0].mclk.vDLL_CNTL =
4821: cpu_to_be32(si_pi->clock_registers.dll_cntl);
...
5021: table->ACPIState.levels[0].mclk.vDLL_CNTL =
5022: cpu_to_be32(dll_cntl);
because such element cannot be accessed without previously allocating
enough dynamic memory for it to exist (which never actually happens).
So, there is an out-of-bounds bug in this case.
That's why struct SISLANDS_SMC_SWSTATE should only be used as type
for object driverState and new struct SISLANDS_SMC_SWSTATE_SINGLE is
created as type for objects initialState, ACPIState and ULVState.
Also, with the change from one-element array to flexible-array member

'xhci_urb_enqueue()' is passed a 'mem_flags' argument, because "URBs may be
submitted in interrupt context" (see comment related to 'usb_submit_urb()'
in 'drivers/usb/core/urb.c')
So this flag should be used in all the calling chain.
Up to now, 'xhci_check_maxpacket()' which is only called from
'xhci_urb_enqueue()', uses GFP_KERNEL.
Be safe and pass the mem_flags to this function as well.

Commit 9ebf30007858 ("xhci: Fix halted endpoint at stop endpoint command
completion") in 5.12 changes how cancelled URBs are given back.
To cancel a URB xhci driver needs to stop the endpoint first.
To clear a halted endpoint xhci driver needs to reset the endpoint.
In rare cases when an endpoint halt (error) races with a endpoint stop we
need to clear the reset before removing, and giving back the cancelled URB.
The above change in 5.12 takes care of this, but it also relies on the
reset endpoint completion handler to give back the cancelled URBs.
There are cases when driver refuses to queue reset endpoint commands,
for example when a link suddenly goes to an inactive error state.
In this case the cancelled URB is never given back.
Fix this by giving back the URB in the stop endpoint if queuing a reset
endpoint command fails.

ACPI 6.4 introduced the "SpaLocationCookie" to the NFIT "System Physical
Address (SPA) Range Structure". The presence of that new field is
indicated by the ACPI_NFIT_LOCATION_COOKIE_VALID flag. Pre-ACPI-6.4
firmware implementations omit the flag and maintain the original size of
the structure.
Update the implementation to check that flag to determine the size
rather than the ACPI 6.4 compliant definition of 'struct
acpi_nfit_system_address' from the Linux ACPICA definitions.
Update the test infrastructure for the new expectations as well, i.e.
continue to emulate the ACPI 6.3 definition of that structure.
Without this fix the kernel fails to validate 'SPA' structures and this
leads to a crash in nfit_get_smbios_id() since that routine assumes that
SPAs are valid if it finds valid SMBIOS tables.
