A mfc_debug_enter() is not balanced by a corresponding mfc_debug_leave(). Add the missing call. Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> --- Compile tested only. Apparently, only a debug message was missing, so don't bother with a Fixes tag, it is not really a bug. --- drivers/media/platform/samsung/s5p-mfc/s5p_mfc.c | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-)
