Subject: [PATCH 2/3] ide: remove superfluous SELECT_MASK() call from do_rw_taskfile()
Date: Mon, 1 Jun 2009 23:53:07 +0200 [thread overview]
Message-ID: <200906012353.07374.bzolnier@gmail.com> (raw)
With ->write_devctl method call (which unmasks drive IRQ) preceding
SELECT_MASK() call there is really no need for the latter.
Moreover with the combination of HPT36x controller and the drive on
the quirk_drives[] list this can result in superfluous enable_irq()
call which in turn will trigger WARN() in __enable_irq().
