This driver uses __fh as the name for the second argument of the ioctl
callbacks. Can you take this opportunity to rename it to either 'fh' or 'priv'?
Generally it's not a good idea to prefix variables with __ for no good reason.
Grepping for __fh also shows two other drivers:
drivers/media/platform/chips-media/coda/coda-common.c:#define fh_to_ctx(__fh)
container_of(__fh, struct coda_ctx, fh)
drivers/media/platform/samsung/s5p-mfc/s5p_mfc_common.h:#define fh_to_ctx(__fh)
container_of(__fh, struct s5p_mfc_ctx, fh)
I think it is a good idea to rename __fh to fh there as well.
