Subject: [8/9] Possible VIA-Rhine free irq issue
Date: Wed, 16 Mar 2005 15:55:45 -0800	[thread overview]
Message-ID: <20050316235545.GG5389@shell0.pdx.osdl.net> (raw)
In-Reply-To: <20050316235336.GY5389@shell0.pdx.osdl.net>

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

----

From: Andres Salomon <dilinger@debian.org>

It seems to me that in the VIA Rhine device driver the requested irq might
not be freed in case the alloc_ring() function fails. alloc_ring()
can fail with a ENOMEM return value because of possible
pci_alloc_consistent() failures.
