From: Wei Yongjun Date: Tue, 19 Jul 2016 11:23:24 +0000 (+0000) Subject: net: axienet: Fix return value check in axienet_probe() X-Git-Tag: v4.8-rc1~140^2~60 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3ad7b1477ef9b01988ac052b02be9cd410c95157;p=karo-tx-linux.git net: axienet: Fix return value check in axienet_probe() In case of error, the function of_parse_phandle() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test. Fixes: 46aa27df8853 ('net: axienet: Use devm_* calls') Signed-off-by: Wei Yongjun Signed-off-by: David S.
