From f2adc4f8aaf272de9ac71dcb18d95ebe05fc3f94 Mon Sep 17 00:00:00 2001 From: Michal Nazarewicz Date: Wed, 16 Jun 2010 12:07:59 +0200 Subject: USB: gadget: composite: usb_string_ids_*() functions added usb_string_ids_tab() and usb_string_ids_n() functions added to the composite framework. The first accepts an array of usb_string object and for each registeres a string id and the second registeres a given number of ids and returns the first. This may simplify string ids registration since gadgets and composite functions won't have to call usb_string_id() several times and each time check for errer status -- all this will be done with a single call.
