[PATCH v3 2/7] drivers: regulator: qcom_spmi: Refactor get_mode/set_mode

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



spmi_regulator_common_get_mode and spmi_regulator_common_set_mode use
multi-level ifs which mirror a switch statement.  Refactor to use a switch
statement to make the code flow more clear.
