[PATCH 06/17] ARM: davinci: dm355: WARN() if clk_get() fails




From: Bartosz Golaszewski <bgolaszewski@xxxxxxxxxxxx>

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.
