From: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx>
commit eca836dfd8386b32f1aae60f8e323218ac6a0b75 upstream.
If tensor_set_bits_atomic() is called with a mask of 0 the function will
just iterate over its bit, not perform any updates and return stack
value of 'ret'.
Also reported by smatch:
drivers/soc/samsung/exynos-pmu.c:129 tensor_set_bits_atomic() error: uninitialized symbol 'ret'.
Fixes: 0b7c6075022c ("soc: samsung: exynos-pmu: Add regmap support for SoCs that protect PMU regs")
