[PATCH 09/17] ARM: davinci: dm646x: WARN() if clk_get() fails

From: Bartosz Golaszewski <hidden>
Date: 2019-01-11 17:22:46
Also in: linux-devicetree, lkml
Subsystem: arm port, the rest, ti davinci machine support · Maintainers: Russell King, Linus Torvalds, Bartosz Golaszewski

From: Bartosz Golaszewski <redacted>

Currently the timer code checks if the clock pointer passed to it is
good (!IS_ERR(clk)). The new clocksource driver expects the clock to
be functional and doesn't perform any checks so emit a warning if
clk_get() fails.
