[PATCH] video: Use bool instead int pointer for get_opt_bool() argument

From: Daniel Wagner
Date: Fri Jan 29 2016 - 08:23:40 EST


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 âintelfb_setupâ:
drivers/video/fbdev/intelfb/intelfbdrv.c:353:39: error: passing argument 3 of âget_opt_boolâ 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
