Subject: [PATCH 05/22] gpiolib: cdev: rename 'filep' and 'filp' to 'file' to be consistent with other use
Rename 'filep' and 'filp' to 'file' to be consistent with other use
and improve readability.
Signed-off-by: Kent Gibson <warthog618@...il.com>

The code was using both "filep" and "filp" and I flip flopped between
which one to change to until looking at code elsewhere in the kernel
where "struct file *file" is the most common and so going with that.
