Subject: [PATCH] mc13783-regulator: fix vaild voltage range checking for
	mc13783_fixed_regulator_set_voltage

In the case of "min_uV == max_uV == mc13783_regulators[id].voltages[0]",
mc13783_fixed_regulator_set_voltage should return 0 instead of -EINVAL.

This patch also adds a missing ">" character for MODULE_AUTHOR, a
trivial fix.
