Since kvfree() already checks if its argument is NULL, an additional check before calling kvfree() is unnecessary and can be removed. Remove both and the following Coccinelle/coccicheck warnings reported by ifnullfree.cocci: WARNING: NULL check before some freeing functions is not needed WARNING: NULL check before some freeing functions is not needed Signed-off-by: Thorsten Blum <thorsten.blum@linux.dev> --- drivers/gpu/drm/vmwgfx/vmwgfx_blit.c | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-)
