Hi Linus,

After merging the gpio tree, today's linux-next build (powerpc
allyesconfig) produced these warnings:

drivers/gpio/gpio-ucb1400.c: In function 'ucb1400_gpio_remove':
drivers/gpio/gpio-ucb1400.c:92:2: warning: ignoring return value of 'gpioch=
ip_remove', declared with attribute warn_unused_result [-Wunused-result]
  gpiochip_remove(&ucb->gc);
  ^

And lots of similar ones.

Introduced by commit 9f5132ae82fd ("gpio: remove all usage of
gpio_remove retval in driver/gpio").

Maybe the __must_check attribute should be removed from the declaration
of the function before removing the retval checking ...

--=20
Cheers,
Stephen Rothwell                    sfr@canb.auug.org.au
