From 7c5881d1625d844cdfcc027a970f0d034b982ba5 Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Mon, 29 Aug 2011 11:54:08 +0300 Subject: [PATCH] usb: gadget: audio: queue wLength-sized requests On Audio class, the wLength field of the Setup packet, contains the data payload size of the following Data phase. Instead of harcoding values, use wLength. This also fixes a bug where Gadget driver had to receive 3 bytes, but it was queueing a ZLP.
