Subject: thermal: cpu_cooling: Change cooling device node
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4a1872ef071c3dbc5bcff6b3750fc61130af0cd6;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

thermal: cpu_cooling: Change cooling device node

Previously, CPU device node was used to register the cooling device.
We chanaged to use the cpufreq device node for registration
even if the specific CPU was turned off.
