gpio: gpio_{request,free}() now required (feature removal) ...
We want to phase out the GPIO "autorequest" mechanism in gpiolib and
require all callers to use gpio_request().
- Update feature-removal-schedule
- Update the documentation now
- Convert the relevant pr_warning() in gpiolib to a WARN()
so folk using this mechanism get a noisy stack dump
Some drivers and board init code will probably need to change.
Implementations not using gpiolib will still be fine; they are already
required to implement gpio_{request,free}() stubs.
