There's no need to zero the buffer, as if the routine gets an error, rc will be different than one. That fixes the following warning: drivers/media/tuners/tda9887.c: In function 'tda9887_status': drivers/media/tuners/tda9887.c:539:2: warning: value computed is not used [-Wunused-value] Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com> --- drivers/media/tuners/tda9887.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
