gpiolib: normalize the return value of gc->get() on behalf of buggy drivers
commit ec2cceadfae72304ca19650f9cac4b2a97b8a2fc upstream.
Commit 86ef402d805d ("gpiolib: sanitize the return value of
gpio_chip::get()") started checking the return value of the .get()
callback in struct gpio_chip. Now - almost a year later - it turns out
that there are quite a few drivers in tree that can break with this
change. Partially revert it: normalize the return value in GPIO core but
also emit a warning.
