Re: [PATCH v6 0/5] media: meson: vdec: Add VP9 decoding support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Neil,

I still get sparse warnings:

drivers/staging/media/meson/vdec/codec_hevc_common.h:15:18: warning: 'vdec_hevc_parser_cmd' defined but not used [-Wunused-const-variable=]
drivers/staging/media/meson/vdec/esparser.c:83: warning: Function parameter or member 'core' not described in 'vp9_update_header'
drivers/staging/media/meson/vdec/esparser.c:83: warning: Function parameter or member 'buf' not described in 'vp9_update_header'
drivers/staging/media/meson/vdec/codec_vp9.c:1333: warning: Function parameter or member 'sess' not described in 'codec_vp9_fetch_rpm'

They look trivial to fix to me.

The v7 series is fine, but I prefer to wait until this v6 is OK as well so I can
combine them in one PR.

Regards,

	Hans
