I just got a kernel update that doesn't work for my PCTV 290e's so I pulled and build the media_build tree and got the below errors which I also got a week ago when I did the same after the previous kernel update and I'm just reporting this without knowing how often errors are fixed or for help if something is wrong at my end. The errors went away after I inserted include of slab.h in those files. /media_build/v4l/radio-isa.c:246:3: error: implicit declaration of function 'kfree' [-Werror=implicit-function-declaration] /media_build/v4l/radio-aztech.c:72:9: error: implicit declaration of function 'kzalloc' [-Werror=implicit-function-declaration] media_build/v4l/radio-rtrack2.c:46:2: error: implicit declaration of function 'kzalloc' [-Werror=implicit-function-declaration] media_build/v4l/radio-typhoon.c:76:9: error: implicit declaration of function 'kzalloc' [-Werror=implicit-function-declaration] media_build/v4l/radio-terratec.c:57:2: error: implicit declaration of function 'kzalloc' [-Werror=implicit-function-declaration] media_build/v4l/radio-aimslab.c:67:9: error: implicit declaration of function 'kzalloc' [-Werror=implicit-function-declaration] media_build/v4l/radio-zoltrix.c:80:9: error: implicit declaration of function 'kzalloc' [-Werror=implicit-function-declaration] media_build/v4l/radio-gemtek.c:183:9: error: implicit declaration of function 'kzalloc' [-Werror=implicit-function-declaration] media_build/v4l/radio-trust.c:57:9: error: implicit declaration of function 'kzalloc' [-Werror=implicit-function-declaration] -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
