Subject: [PATCH 02/19] pcmcia: IRQ_TYPE_EXCLUSIVE is long obsoleted
Date: Sun, 05 Oct 2008 17:35:41 +0100 [thread overview]
Message-ID: <20081005163526.3799.57100.stgit@localhost.localdomain> (raw)
In-Reply-To: <20081005163302.3799.61899.stgit@localhost.localdomain>
Switch more drivers to dynamic sharing after checking their IRQ handlers
use dev_id and are robust
Signed-off-by: Alan Cox <alan@redhat.com>
