From d470df3bc5e1a9cd38995b55c918d9ecdda141e1 Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Mon, 22 Jul 2019 15:17:40 +0200 Subject: ARM: davinci: WARN_ON() if clk_get() fails 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. Apply this to all davinci platforms.
