From: Sebastian Andrzej Siewior Date: Tue, 28 Aug 2012 20:37:13 +0000 (+0200) Subject: usb: remove libusual X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f61870ee6f8cc77a844e22f26c58028078df7167;p=linux-beck.git usb: remove libusual The "Low Performance USB Block driver" has been removed which a user of libusual. Now we have only the usb-storage driver as the only driver in tree. This makes libusual needless. This patch removes libusal, fixes up all users. The usual-table is now linked into usb-storage. usb_usual.h remains in public include directory because some staging users seem to need it.
