This should be moved to a header. checkpatch gives me:
Applying: media: mtk-vcodec: remove unneeded proxy functions
WARNING: externs should be avoided in .c files
#79: FILE: drivers/media/platform/mtk-vcodec/vdec_drv_if.c:14:
+extern const struct vdec_common_if vdec_vp8_if;
WARNING: externs should be avoided in .c files
#80: FILE: drivers/media/platform/mtk-vcodec/vdec_drv_if.c:15:
+extern const struct vdec_common_if vdec_vp9_if;
WARNING: externs should be avoided in .c files
#156: FILE: drivers/media/platform/mtk-vcodec/venc_drv_if.c:15:
+extern const struct venc_common_if venc_vp8_if;
And I agree with checkpatch here.
I'll drop this patch from the series, but I'll take the others.
Regards,
Hans
