Subject: media: dvb_vb2: Use the sanitized value after processed by VB2 core
X-Git-Tag: v5.15~9456^2~118
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=19393a03577b4572f51364d9e12c0c695979243d;p=platform%2Fkernel%2Flinux-starfive.git

media: dvb_vb2: Use the sanitized value after processed by VB2 core

if the number of buffers requested by the user is too big, the
VB core will truncate to a valid value.

Use it, instead of what the user requested.
