[PATCH 1/1] drivers: android: Cleanup warnings

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
