-Subject: [PATCH] net: rfkill: gpio: use
- clk_prepare_enable/clk_disable_unprepare
-
-rfkill-gpio calls clk_enable() without first calling clk_prepare(),
-resulting in a warning and no effect. Switch to clk_prepare_enable()
-and clk_disable_unprepare.

-Subject: [PATCH] net: rfkill: gpio: fix reversed clock enable state
-
-rfkill-gpio has clk_enabled = blocked, which is true when rfkill
-blocks the device. This results in calling clock enable/disable at
-the wrong time. Reversing the value fixes this.

-Some devices, such as Broadcom Bluetooth devices, require a specific
-clock rate for the clock tied to the rfkill device. Add clock-frequency
