Pull drm updates from Dave Airlie:
"I Was Almost Tempted To Capitalise Every Word, but then I decided I
couldn't read it myself!
I've also got one pull request for the sti driver outstanding. It
relied on a commit in Greg's tree and I didn't find out in time, that
commit is in your tree now so I might send that along once this is
merged.
I also had the accidental misfortune to have access to a Skylake on my
desk for a few days, and I've had to encourage Intel to try harder,
which seems to be happening now.
Here is the main drm-next pull request for 4.4.
Highlights:

(From Eric Anholt at Broadcom.)

This patch changes no code, it just fixes the whitespacing. Operators

For the npwm property the PWM sysfs interface already made use of the
DEVICE_ATTR_RO macro. This patch expands this to the other sysfs
properties so that the code base is concise and makes use of this
helpful macro.
This has the advantage of slightly reducing the code size, improving
readability and no longer using magic values for permissions.

When looking up a PWM using the lookup table, assume that all entries
will have been added already, so failure to find a match means that no
corresponding entry has been registered.
This fixes an issue where -EPROBE_DEFER would be returned if the PWM
lookup table is empty. After this fix, -EPROBE_DEFER is reserved for
situations where no provider has yet registered for a matching entry.

The pwm_enable() function didn't clear the enabled bit if a call to the
driver's ->enable() callback returned an error. The result was that the
state of the PWM core was wrong. Clearing the bit when enable returns
an error ensures the state is properly set.

After changing an interface's MTU, then bringing the interface down and
back up again, I immediately saw tons of kernel messages like below.
The reason for this bad behavior is mvneta_rxq_drop_pkts(), which calls
dma_unmap_single() on already-freed memory. So we need to switch the
order of those two operations.

The fixed_phy infrastructure is done in a way that is optional,
by providing 'static inline' helper functions doing nothing in
include/linux/phy_fixed.h for all its APIs. However, three out
of the four users (DSA, BCMGENET, and SYSTEMPORT) always
'select FIXED_PHY', presumably because they need that.
MVNETA is the fourth one, and if that is built-in but FIXED_PHY
is configured as a loadable module, we get a link error:
drivers/built-in.o: In function `mvneta_fixed_link_update':
fpga-mgr.c:(.text+0x33ed80): undefined reference to `fixed_phy_update_state'
Presumably this driver has the same dependency as the others,
so this patch also uses 'select' to ensure that the fixed-phy
support is built-in.

__compat_only_sysfs_link_entry_to_kobj() was unconditionally called for
TPM1 chips, which caused crash on Acer C720 laptop where DSM for the
ACPI object did not exist.
There are two reasons for unwanted behavior:
* The code did not check whether
__compat_only_sysfs_link_entry_to_kobj() returned -ENOENT. This is
OK. It just meanst that ppi is not available.
* The code did not clean up properly. Compat link should added only
after all other init is done.
This patch sorts out these issues.

If the probing finishes without success, it will leave the value 15 in
the TPM_IRQ_VECTOR register. If the driver is unloaded and reloaded, it
will "think" that the hardware had been programmed with IRQ 15, and will
not probe again.
This patch restores the original value in the IO memory if no IRQ is
probed.

introduced with the first NFC pull request for 4.4.
We have:
- Fix nfcmrvl SPI driver potential build error due to a broken Kconfig
dependency.
- A few fixes for the firmware download implementation for the nfcmrvl
UART driver.
- A GPIO allocation leak for the nfcmrvl driver.
- One code simplification for the nfcmrvl DT handling.

mcp794xx alarm registers must be written in BCD format. However, the
alarm programming logic neglected this by adding one to the value
after bin2bcd conversion has been already done, writing bad values
to month register in case the alarm being set is in October. In this
case, the alarm month value becomes 0x0a instead of the expected 0x10.
Fix by moving the +1 addition within the bin2bcd call also.

The davinci rtc driver uses the module_platform_driver_probe()
helper to call the probe function and mark it as __init, but
it also puts a reference into its davinci_rtc_driver function.
This will crash if we ever get a deferred probe and the probe
function is called again after the init section has been removed.
kbuild warns about this:
WARNING: vmlinux.o(.data+0x1aa2b4): Section mismatch in reference from the variable davinci_rtc_driver to the function .init.text:davinci_rtc_probe()
The variable davinci_rtc_driver references
the function __init davinci_rtc_probe()

which avoids those problems.
