    Subject[PATCH 4.14 13/91] 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.
