Subject: [COMMON] thermal: core: Check thermal_zone mode.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b4bb592d09a5ce8474a4d4f0d0e13c3ba61b9f1d;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[COMMON] thermal: core: Check thermal_zone mode.

If mode is THERMAL_DEVICE_DISABLED,
skip reading temperature and throttling.
