    Subject[PATCH 3.12 110/123] Input: serio - fix blocking of parport
    Date
    From: Sudip Mukherjee <sudipm.mukherjee@gmail.com>

    3.12-stable review patch. If anyone has any objections, please let me know.

    ===============

    commit 1a5e251996e1b602f2ddc9261ee9de0ca1875bfa upstream.

    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.
