Re: [PATCH] USB and Driver Core patches for 2.6.10

ChangeSet 1.1938.444.33, 2004/12/22 13:50:21-08:00, davej@xxxxxxxxxx

[PATCH] driver core: Fix up vesafb failure probing.

bus.c file invokes a probe callback for most devices in a list, then checks
for -ENODEV return ("no such device"), if so it remains silent. However, some
drivers (including vesafb.c) may return -ENXIO ("no such device or address"),
which is indeed error -6.

I shut up the warning with the attached patch, that basically ignores
both -ENODEV and -ENXIO.
