[PATCH 0/2] gpiolib: cdev: fixes for split from gpiolib.c

[Kent Gibson]

A couple of minor fixes for the recent split from gpiolib.c:
The first fixes a couple of W=1 build warnings by including the module's
own header.
The second fixes the file comment.  This was in v3 of the split patch,
but v2 got merged...
