Subject: [PATCH] video: Use bool instead int pointer for get_opt_bool() argument
Date: Fri, 29 Jan 2016 14:23:25 +0100	[thread overview]
Message-ID: <1454073805-14443-1-git-send-email-daniel.wagner@bmw-carit.de> (raw)
In-Reply-To: <1453992270-4688-1-git-send-email-daniel.wagner@bmw-carit.de>

As the function name already indicates that get_opt_bool() parses
for a bool. It is not a surprise that compiler is complaining
about it when -Werror=incompatible-pointer-types is used:

drivers/video/fbdev/intelfb/intelfbdrv.c: In function ‘intelfb_setup’:
drivers/video/fbdev/intelfb/intelfbdrv.c:353:39: error: passing argument 3 of ‘get_opt_bool’ from incompatible pointer type [-Werror=incompatible-pointer-types]
   if (get_opt_bool(this_opt, "accel", &accel))

Hi,

In the 'simple wait queue support' series is a patch
which turns on -Werror=incompatible-pointer-types which will
result in a compile error for intelfb.

https://lkml.org/lkml/2016/1/28/462

Even if that patch wont make it, this one makes sense (at least
for me :))

I'll prepend this patch to the next version of the series in order
to see if I got rid of all incompatible pointer types errors caught
by the kbuild test robot.

cheers,
daniel
