thermal/drivers/exynos: Fix an error code in exynos_tmu_probe()

2021-09-26T11:39:47Z

commit 02d438f62c05f0d055ceeedf12a2f8796b258c08 upstream. This error path return success but it should propagate the negative error code from devm_clk_get().

thermal: exynos: Reduce severity of too early temperature read

2018-06-01T21:32:01Z

Thermal core tries to read temperature during sensor registering in thermal_zone_of_sensor_register(). In that time Exynos TMU driver and hardware are not yet initialized. Commit 0eb875d88aaa ("thermal: exynos: Reading temperature makes sense only when TMU is turned on") added a boolean flag to prevent reading bogus temperature in such case but it exposed warning message during boot: [ 3.864913] thermal thermal_zone0: failed to read out thermal zone (-22) Return EAGAIN in such case to skip omitting such message because it might mislead user.
