From e7ad21e00eab6b77fb9b5cd79512b7dee473f476 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Bj=C3=B8rn=20Mork?= Date: Sun, 15 Jul 2012 16:47:39 +0200 Subject: [PATCH] USB: qcserial: support generic Qualcomm serial ports MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit No need to verify the interface layout when doing interface number based matching. We can safely trust the device ID table in this case. This allows the driver to support any USB interface layout for non-Gobi 1k/2k+ devices.
