Subject: media: mc: mc-entity.c: Use bitmap_zalloc() when applicable Author: Christophe JAILLET <[email protected]> Date: Wed Dec 1 23:19:40 2021 +0100 'ent_enum->bmap' is a bitmap. So use 'bitmap_zalloc()' to simplify code, improve the semantic and avoid some open-coded arithmetic in allocator arguments. Also change the corresponding 'kfree()' into 'bitmap_free()' to keep consistency. While at it, remove a useless 'bitmap_zero()'.
