From 7fa0043d5c74c6ef6ab58ecf7528fd33c6cb07a8 Mon Sep 17 00:00:00 2001 From: Robert Hancock Date: Tue, 11 Jun 2019 10:56:02 -0600 Subject: [PATCH] net: axienet: move use of resource after validity check We were accessing the pointer returned from platform_get_resource before checking if it was valid, causing an oops if it was not. Move this access after the call to devm_ioremap_resource which does the validity check. Signed-off-by: Robert Hancock Reviewed-by: Andrew Lunn Signed-off-by: David S.
