In the Linux kernel, the following vulnerability has been resolved:
clk: qcom: gfx3d: add parent to parent request map
After commit d228ece36345 ("clk: divider: remove round rate() in favor
of determine rate()") determining GFX3D clock rate crashes, because the
passed parent map doesn't provide the expected best parent hw clock
(with the roundd rate path before the offending commit the
best parent hw was ignored).
Set the field in parent req in addition to setting it in the req,
fixing the crash.
