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)) Signed-off-by: Daniel Wagner <daniel.wagner@xxxxxxxxxxxx> Reported-by: Fengguang Wu <fengguang.wu@xxxxxxxxx> --- [resend because Maik's emial address bounced last try] 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 drivers/video/fbdev/intelfb/intelfbdrv.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/video/fbdev/intelfb/intelfbdrv.c b/drivers/video/fbdev/intelfb/intelfbdrv.c index bbec737..bf20744 100644 --- a/drivers/video/fbdev/intelfb/intelfbdrv.c +++ b/drivers/video/fbdev/intelfb/intelfbdrv.c @@ -302,7 +302,7 @@ static __inline__ int get_opt_int(const char *this_opt, const char *name, } static __inline__ int get_opt_bool(const char *this_opt, const char *name, - int *ret) + bool *ret) { if (!ret) return 0; -- 2.5.0 -- To unsubscribe from this list: send the line "unsubscribe linux-fbdev" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
