2016-03-11staging: netlogic: Replacing pr_err with dev_err after the call to devm_kzallocG Pooja Shamili
The function devm_kzalloc has a first argument of type struct device *. This is the type of argument required by printing functions such as dev_info, dev_err, etc. Thus, functions like pr_info should not normally be used after a call to devm_kzalloc. Thus, all pr_err occurances are replaced with dev_err function calls Signed-off-by: G Pooja Shamili <poojashamili@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2016-03-11staging: ion: debugfs invalid gfp maskDerek Yerger
The current code attempts assignment of -1 to an unsigned type.

2016-03-11staging: rts5208: Replace pci_enable_device with pcim_enable_deviceAmitoj Kaur Chawla
Devm_ functions allocate memory that is automatically freed when a driver detaches. Replace pci_enable_device with pcim_enable_device. Remove unnecessary pci_disable_device and pci_release_regions from probe and remove functions in rts5208 driver since pcim_enable_device contains a call to pcim_release which contains calls to both pci_disable_device and pci_release_regions.

2016-03-11staging: speakup: Replace del_timer with del_timer_syncAmitoj Kaur Chawla
Use del_timer_sync to ensure timer is stopped on all CPUs before the driver exists and the timer should not run when the module is being removed. Since the timer is not called from an interrupt context, this change is safe and will not cause deadlock. The Coccinelle semantic patch used to make this change is as follows: // <smpl> @r@ declarer name module_exit; identifier ex; @@ module_exit(ex); @@ identifier r.ex; @@ ex(...) { <... - del_timer + del_timer_sync (...) ...> } // </smpl> Signed-off-by: Amitoj Kaur Chawla <amitoj1606@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2016-03-11staging: iio: adc: Replace of_iomap() with devm_ioremap_resource()Amitoj Kaur Chawla
The adc driver uses of_iomap() which doesn't request the resource and isn't device managed so error handling is needed. of_iomap() is mainly used in cases where there is no driver or struct device so a switch to devm_ functions is required. This patch switches to use devm_ioremap_resource() instead which automatically requests the resource and is freed when the driver detaches. Removed the error handling to unmap I/O registers i.e. iounmap() in probe and remove functions of this driver and consequently removed an unnecessary label.
