From e83980455c8c7eb066405de512be7c4bace3ac4d Mon Sep 17 00:00:00 2001 From: Jason Wang Date: Fri, 29 May 2015 14:15:25 +0800 Subject: virtio: device_plugged() can fail This patch passes error pointer to transport specific device_plugged() callback. Through this way, device_plugged() can do some transport specific check and fail. This will be uesd by following patches that check the number of virtqueues against the transport limitation.
