[PATCH v2 20/30] gpio: nomadik: make clock optional

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


Not all platforms using this platform driver expose a clock for this
GPIO controller. Turn devm_clk_get() into devm_clk_get_optional() to
avoid failing when no clocks are provided.
