From 1a5e251996e1b602f2ddc9261ee9de0ca1875bfa Mon Sep 17 00:00:00 2001 From: Sudip Mukherjee Date: Sun, 27 Sep 2015 17:13:55 -0700 Subject: [PATCH] Input: serio - fix blocking of parport If parkbd_allocate_serio() fails to allocate memory we are releasing the parport but we missed unregistering the device. As a result this device with exclusive access to that parport remains registered. And no other device will be able to use that parport even though this driver has failed to load.
