From 42d452dc4a3674bbe53fa80f00f31f72385252dd Mon Sep 17 00:00:00 2001 From: "Lendacky, Thomas" Date: Wed, 28 Jun 2017 13:42:16 -0500 Subject: [PATCH] amd-xgbe: Handle return code from software reset function Currently the function that performs a software reset of the hardware provides a return code. During driver probe check this return code and exit with an error if the software reset fails. Signed-off-by: Tom Lendacky Signed-off-by: David S.
