36bcba973a [media] mtk_vcodec_dec: return error at mtk_vdec_pic_info_update()
Gcc 7.1 complains that:

	drivers/media/platform/mtk-vcodec/mtk_vcodec_dec.c: In function 'mtk_vdec_pic_info_update':
	drivers/media/platform/mtk-vcodec/mtk_vcodec_dec.c:284:6: warning: variable 'ret' set but not used [-Wunused-but-set-variable]
	  int ret;
	      ^~~

Indeed, if debug is disabled, "ret" is never used. The best
fix for it seems to make the fuction to return an error code.

e8a2a41ee2 [media] mtk-vcodec: check the vp9 decoder buffer index from VPU
VPU firmware has a bug and may return invalid buffer index for
some vp9 videos. Check the buffer indexes before accessing the
buffer.

9eeb0ed0f3 [media] mtk-vcodec: fix build warnings without DEBUG
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.

b7ccb9fb79 [media] mtk-vcodec: add index check in decoder vidioc_qbuf
vb2_qbuf will check the buffer index. If a driver overrides
vidioc_qbuf and use the buffer index, the driver needs to check
the index.
