[media] s5p-fimc: dubious one-bit signed bitfields
> From: Dan Carpenter [mailto:error27@gmail.com] > > These are signed so instead of being 1 and 0 as intended they are -1 and > 0. It doesn't cause a bug in the current code but Sparse warns about > it: > > drivers/media/video/s5p-fimc/fimc-core.h:226:28: > error: dubious one-bit signed bitfield > struct fimc_scaler { > - int scaleup_h:1; > - int scaleup_v:1; > - int copy_mode:1; > - int enabled:1; > + unsigned int scaleup_h:1; > + unsigned int caleup_v:1; > + unsigned int copy_mode:1; > + unsigned int enabled:1; In general I agree, however this patch would change scaleup_v:1 to caleup_v, so it cannot be applied in current form.
