[PATCH] [101/139] Revert "USB: gadget: Allow function access to device ID data during bind()"

From: Andi Kleen
Date: Tue Feb 01 2011 - 19:55:58 EST


2.6.35-longterm review patch. If anyone has any objections, please let me know.

------------------
From: Greg Kroah-Hartman <gregkh@xxxxxxx>

commit dbb442b85a1d82f91cfe0524c4f9b3a5196a10ca upstream.

This reverts commit 1ab83238740ff1e1773d5c13ecac43c60cf4aec4.

Turns out this doesn't allow for the device ids to be overridden
properly, so we need to revert the thing.
