From b0ef489e2a9cfcb64e4a20f308023afaea9db8d3 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Fri, 28 Aug 2020 17:26:37 +0200 Subject: [PATCH] dmaengine: xilinx: Simplify with dev_err_probe() Common pattern of handling deferred probe can be simplified with dev_err_probe(). Less code and the error value gets printed.
