[PATCH 2/4] media: mediatek: vcodec: remove redundant return value of vdec_vp9_slice_setup_prob_buffer()

[Haoxiang Li]

vdec_vp9_slice_setup_prob_buffer() never fails, remove 'return 0' from
vdec_vp9_slice_setup_prob_buffer() and modify its signature.
Also, remove the return value check in vdec_vp9_slice_setup_single()
and vdec_vp9_slice_setup_lat().
