[QUOTE="RyLe, post: 1166140, member: 377555"] Hi I updated to kernel 6.11.3-200.fc40 . There are a bunch of warnings for min3 and max3 redefinitions like this when I try to compile the blindscan driver: [ICODE]/home/ryle/blindscan_kernel/neumo_media_build/v4l/compat.h:239:9: warning: "max3" redefined 239 | #define max3(x, y, z) max((typeof(x))max(x, y), z) | ^~~~ ./include/linux/minmax.h:176:9: note: this is the location of the previous definition 176 | #define max3(x, y, z) \ | ^~~~[/ICODE] and at least one compilation error: [ICODE]/home/ryle/blindscan_kernel/neumo_media_build/v4l/bttv-gpio.c:61:19: error: initialization of 'int (*)(struct device *, const struct device_driver *)' from incompatible pointer type 'int (*)(struct device *, struct device_driver *)' [-Wincompatible-pointer-types] 61 | .match = &bttv_sub_bus_match, | ^ /home/ryle/blindscan_kernel/neumo_media_build/v4l/bttv-gpio.c:61:19: note: (near initialization for 'bttv_sub_bus_type.match') make[4]: *** [scripts/Makefile.build:244: /home/ryle/blindscan_kernel/neumo_media_build/v4l/bttv-gpio.o] Error 1[/ICODE] In the mean time, I managed to compile the driver adding [ICODE]EXTRA_CFLAGS += -Wno-incompatible-pointer-types[/ICODE] to [ICODE]~/blindscan_kernel/neumo_media_build/v4l/Makefile[/ICODE] not pretty, but it worked.
