[PATCH v2 0/2] Fix mtk-hdmi-mt8195 unitialized variable usage and clock rate calculation

Posted by Guillaume Ranquet 1 year, 7 months ago

I've received a report from kernel test report [1] that a variable was used
unitialized in the mtk8195 hdmi phy code.

I've upon fixing that issue found out that the clock rate calculation
was erroneous since the calculus was moved to div_u64.

I'm providing those two fixes on top of 45810d486bb44 from the linux-phy
repository [2].
