Subject: [PATCH] staging: iio: ad9834: add a check for devm_clk_get
Date: Wed, 16 Oct 2019 22:25:40 +0800 [thread overview]
Message-ID: <20191016142540.26450-1-hslester96@gmail.com> (raw)
ad9834_probe misses a check for devm_clk_get and may cause problems.
Add a check like what ad9832 does to fix it.
