From 9b2cef31f2823558eb92a35624d37439599f3f9f Mon Sep 17 00:00:00 2001 From: Bill Pemberton Date: Thu, 5 Aug 2010 17:01:06 -0400 Subject: USB: ssu100: refine process_packet in ssu100 The status information does not appear at the start of each incoming packet so the check for len < 4 at the start of ssu100_process_packet is wrong. Remove it.
