Subject[PATCH 5.4 036/191] clocksource/drivers/asm9260: Add a check for of_clk_get
Date
From: Chuhong Yuan <hslester96@gmail.com>

[ Upstream commit 6e001f6a4cc73cd06fc7b8c633bc4906c33dd8ad ]

asm9260_timer_init misses a check for of_clk_get.
Add a check for it and print errors like other clocksource drivers.
