Subject: drm/dp-mst-helper: Avoid reading uninitialized value
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7389ad4b6515c2de6402bfafdfebf0b319790d16;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/dp-mst-helper: Avoid reading uninitialized value

A static analysis tool tells me that we could try to read an
uninitialized 'ret' value. Plug that.
