[media] vcodec: mediatek: Remove double parentheses

2017-04-05T18:09:20Z

The extra pairs of parentheses are not needed and cause clang warnings like this: drivers/media/platform/mtk-vcodec/venc/venc_vp8_if.c:158:32: error: equality comparison with extraneous parentheses [-Werror,-Wparentheses-equality] if ((inst->work_bufs[i].size == 0)) ~~~~~~~~~~~~~~~~~~~~~~~~^~~~ drivers/media/platform/mtk-vcodec/venc/venc_vp8_if.c:158:32: note: remove extraneous parentheses around the comparison to silence this warning if ((inst->work_bufs[i].size == 0)) ~ ^ ~ drivers/media/platform/mtk-vcodec/venc/venc_vp8_if.c:158:32: note: use '=' to turn this equality comparison into an assignment if ((inst->work_bufs[i].size == 0)) ^~ = Signed-off-by: Matthias Kaehlcke Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] mtk-vcodec: fix build warnings without DEBUG

2017-02-08T14:08:20Z

After removing DEBUG from mtk_vcodec_util.h, some build warnings are generated as the following: .../drivers/media/platform/mtk-vcodec/vdec_vpu_if.c: In function 'vcodec_vpu_send_msg': .../drivers/media/platform/mtk-vcodec/vdec_vpu_if.c:73:11: warning: unused variable 'msg_id' [-Wunused-variable] uint32_t msg_id = *(uint32_t *)msg; ^ .../drivers/media/platform/mtk-vcodec/mtk_vcodec_dec.c: In function 'vb2ops_vdec_buf_queue': .../drivers/media/platform/mtk-vcodec/mtk_vcodec_dec.c:1129:7: warning: unused variable 'log_level' [-Wunused-variable] int log_level = ret ? 0 : 1; ^ .../drivers/media/platform/mtk-vcodec/venc_vpu_if.c: In function 'vpu_enc_send_msg': .../drivers/media/platform/mtk-vcodec/venc_vpu_if.c:82:12: warning: unused variable 'msg_id' [-Wunused-variable] uint32_t msg_id = *(uint32_t *)msg; ^ It is because mtk_vcodec_debug() and mtk_vcodec_err() are defined as empty macros. Without DEBUG definition, the variable for debugging is not used anymore. Fixing build warnings by moving the assignment of the variable to the argument of mtk_vcodec_debug() and mtk_vcodec_err(). Within the patch, build pass with/without DEBUG definition, and functions still work fine. Signed-off-by: Minghsiu Tsai Reviewed-by: Daniel Kurtz Signed-off-by: Mauro Carvalho Chehab
