Subject: drm/amd/display: Reset pipe count when iterating for DET override
X-Git-Tag: v6.0-rc1~138^2~2^2~24
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f46e3f28f89b893685ec9204405677dac410d8ad;p=thirdparty%2Flinux.git

drm/amd/display: Reset pipe count when iterating for DET override

[Why]
Coding error in DET allocation was resulting in too few DET segments
being allocated, causing underflow.

[How]
Reset pipe count each time we begin iterating through pipes for a stream.
