Patch is also broken: it introduces some weird stuff there. Even after removing
it,
still doesn't compile:
drivers/media/common/tuners/mt2063.c: In function ‘MT2063_ChooseFirstIF’:
drivers/media/common/tuners/mt2063.c:398:26: error: array type has incomplete
element type
drivers/media/common/tuners/mt2063.c:429:7: error: implicit declaration of
function ‘floor’ [-Werror=implicit-function-declaration]
drivers/media/common/tuners/mt2063.c:433:7: error: implicit declaration of
function ‘ceil’ [-Werror=implicit-function-declaration]
drivers/media/common/tuners/mt2063.c:398:26: warning: unused variable ‘zones’
[-Wunused-variable]
cc1: some warnings being treated as errors
