[RFC: 2.6 patch] remove the USB_STORAGE_ONETOUCH driver

From: Adrian Bunk
Date: Sun Oct 28 2007 - 11:52:20 EST


Nearly two years ago, USB_STORAGE_ONETOUCH got a dependency on !PM.
Considering that this also implies that the driver is not available
e.g. when ACPI is enabled in the kernel that's not far from a dependency
on BROKEN.

This patch therefore removes this driver.
