[PATCH 5/5] thermal: exynos: Directly return 0 instead of using local ret variable

Krzysztof Kozlowski
2015-10-08T05:34:06Z

The 'ret' variable in exynos5440_tmu_initialize() is initialized to 0
and returned as is. Replace it with direct return statement. This also
fixes coccinelle warning:
drivers/thermal/samsung/exynos_tmu.c:611:5-8: Unneeded variable: "ret". Return "0" on line 654
