Krzysztof Kozlowski 8fd332aebd soc: samsung: exynos-pmu: Fix uninitialized ret in tensor_set_bits_atomic() 
commit eca836dfd8 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'.
