Driver is stable. Remove DEBUG definition from driver.

There are debug message in /var/log/messages if DEBUG is defined,
such as:
[MTK_V4L2] level=0 fops_vcodec_open(),170: decoder capability 0
[MTK_V4L2] level=0 fops_vcodec_open(),177: 16000000.vcodec decoder [0]
[MTK_V4L2] level=0 fops_vcodec_release(),200: [0] decoder

After this patch, building the Kernel with W=1 now shows warnings:

drivers/media/platform/mtk-vcodec/mtk_vcodec_dec_pm.c: In function 'mtk_vcodec_dec_pw_on':
drivers/media/platform/mtk-vcodec/mtk_vcodec_dec_pm.c:114:51: warning: suggest braces around empty body in an 'if' statement [-Wempty-body]
   mtk_v4l2_err("pm_runtime_get_sync fail %d", ret);
                                                   ^

I wrote a patch fixing it, as this is really a trivial issue.

Yet, after that, this one still remains:


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;
      ^~~


Shouldn't be mtk_vdec_pic_info_update() returning an error code?


Also, IMHO, at least errors should be shown at dmesg.

Thanks,
Mauro

Got it. We will upstream patch to fix warning and add dmesg when error.
