staging: android: ion: Fix return value check in hi6220_ion_probe()
In case of error, the function ion_device_create() returns ERR_PTR() and
never returns NULL. The NULL test in the return value check should be
replaced with IS_ERR().
Instead of storing the return value of a function call into a variable and
then returning it, we can club the two into a single return statement. This
change was made using the following semantic patch by Coccinelle:
add braces to if/else clause to fix the checkpatch issue braces {}
should be used on all arms of if/else block. Does not affect flow
because only single statement inside if/else block.
staging: gs_fpgaboot: Remove FSF address from GPL notice
This patch fixes the checkpatch.pl warning:

includes a copy of the GPL.

Therefore, remove it. The static unused functions were detected
using Coccinelle but the change was done by hand.
