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


From: Maciej Szmigiero <mhej@xxxxx>

commit 72a012ce0a02c6c616676a24b40ff81d1aaeafda upstream.

My Galaxy Spica needs this quirk when in modem mode, otherwise
it causes endless USB bus resets and is unusable in this mode.

Unfortunately Samsung decided to reuse ID of its old CDMA phone SGH-I500
for the modem part.
That's why in addition to this patch the visor driver must be prevented
from binding to SPH-I500 ID, so ACM driver can do that.
