Subject: [PATCH AUTOSEL 4.9 11/42] clocksource/drivers/asm9260: Add a check for of_clk_get
Date: Wed, 11 Dec 2019 10:34:39 -0500 [thread overview]
Message-ID: <20191211153510.23861-11-sashal@kernel.org> (raw)
In-Reply-To: <20191211153510.23861-1-sashal@kernel.org>
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.
