Subject: [PATCH 7/8] ide: make legacy IDE VLB modules check for the "probe" kernel params
Date: Wed, 14 Feb 2007 02:57:12 +0100 [thread overview]
Message-ID: <20070214015712.4619.78705.sendpatchset@localhost.localdomain> (raw)
In-Reply-To: <20070214015603.4619.41923.sendpatchset@localhost.localdomain>
[PATCH] ide: make legacy IDE VLB modules check for the "probe" kernel params
Legacy IDE VLB host drivers didn't check for "probe" options when compiled
as modules, which was obviously wrong as we don't want module to poke at
random I/O ports by simply loading it. Fix it by adding "probe" module param
to legacy IDE VLB host drivers and obsolete old "ide0=dtc2278", "ide0=ht6560b",
"ide0=qd65xx", "ide0=ali14xx", "ide0=umc8672" IDE driver options.
