From e687cd19f1cb9d3bbb16146fe7a8740cf836e481 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Wed, 19 Oct 2016 13:23:50 +0000 Subject: dmaengine: st_fdma: Fix the error return code in st_fdma_probe() In case of error, the function st_slim_rproc_alloc() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().
