H A Dexynos_tmu.cdiff c8da6cdef57b459ac0fd5d9d348f8460a575ae90 Mon Apr 16 12:11:53 CEST 2018 Marek Szyprowski <m.szyprowski@samsung.com> thermal: exynos: Propagate error value from tmu_read()

tmu_read() in case of Exynos4210 might return error for out of bound
values. Current code ignores such value, what leads to reporting critical
temperature value. Add proper error code propagation to exynos_get_temp()
function.
