[PATCH 0/4] gpiolib: some fixup patches

From: Alexandre Courbot
Date: Wed Feb 13 2013 - 02:03:20 EST


This short series is a fixup to patch 6/9 of my previous series ("gpiolib: use
descriptors internally"), which mainly addresses issues raised by Linus W. in
this patch and a few other minor ones caught while proof-reading gpiolib.

First patch is the most significant. It mostly avoids oopses when passing an
invalid GPIO to some functions. Also gpio_get/set_value*() now return 0 when
given an invalid GPIO number instead of oopsing. I tend to think that's an
improvement, but if it's not please let me know.

Ideally these patches should be melded into the above-mentioned patch since
they were intended to become a new revision, but I leave that decision to
Grant's discretion.

This patchset has been thoroughly tested on Tegra 2/Ventana with a GPIO
backlight driver and the sysfs interface.

Alexandre Courbot (4):
gpiolib: check descriptors validity before use
gpiolib: use const parameters when possible
gpiolib: move comment to right function
gpiolib: rename local offset variables to "hwgpio"
