From c578abbc20762aa58e390e55252959853eeea17e Mon Sep 17 00:00:00 2001 From: Cornelia Huck Date: Mon, 27 Nov 2006 10:35:10 +0100 Subject: [PATCH] driver core: Don't stop probing on ->probe errors. Don't stop on the first ->probe error that is not -ENODEV/-ENXIO. There might be a driver registered returning an unresonable return code, and this stops probing completely even though it may make sense to try the next possible driver. At worst, we may end up with an unbound device.
