From 37282485dd4c95c4a637cfa263a0753216f1ec24 Mon Sep 17 00:00:00 2001 From: Russell King Date: Mon, 10 Apr 2017 16:28:04 +0100 Subject: [PATCH] net: mvmdio: disable interrupts in driver failure path When the mvmdio driver has an interrupt, it enables the "done" interrupt after requesting its interrupt handler. However, probe failure results in the interrupt being left enabled. Disable it on the failure path. Signed-off-by: Russell King Reviewed-by: Andrew Lunn Signed-off-by: David S.
