Subject: [PATCH 5/5] clocksource/drivers/asm9260: Add a check for of_clk_get
Date: Mon,  4 Nov 2019 15:22:57 +0100	[thread overview]
Message-ID: <20191104142257.30029-5-daniel.lezcano@linaro.org> (raw)
In-Reply-To: <20191104142257.30029-1-daniel.lezcano@linaro.org>

From: Chuhong Yuan <hslester96@gmail.com>

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