Subject: [PATCH -next 4/4] dmaengine: xilinx_dma: Remove clk_get error message for probe defer
Date: Thu, 26 Sep 2019 16:21:00 +0530	[thread overview]
Message-ID: <1569495060-18117-5-git-send-email-radhey.shyam.pandey@xilinx.com> (raw)
In-Reply-To: <1569495060-18117-1-git-send-email-radhey.shyam.pandey@xilinx.com>

In dma probe, the driver checks for devm_clk_get return and print error
message in the failing case. However for -EPROBE_DEFER this message is
confusing so avoid it.
