Subject: [PATCH 1/1] drivers: android: Cleanup warnings
Ran checkpatch across the entire drivers/android
directory and fixed all relevant warnings. Summary
of changes done:
-> Convert all symbolic permissions into their
octal equivalents.
-> Use "%s", __func__ in logging macros where the
function name was previously hard-coded.
-> Add a blank line to separate declarations from
statements according to the kernel coding style
guidelines.
-> Fix linelength issues wherever possible.
-> Fix-up a commented out statement to use // in place
of /* */ to silence checkpatch.
Most line-length warnings were ignored in favor
of code readability.
