Subject[PATCH 1/1] clk: clk-wm831x: fix a logic error
Message-ID<sJt2x-aP-1@gated-at.bofh.it>
Fix bug https://bugzilla.kernel.org/show_bug.cgi?id=188561. Function
wm831x_clkout_is_prepared() returns "true" when it fails to read
CLOCK_CONTROL_1. "true" means the device is already prepared. So
return "true" on the read failure seems improper.
