From 929b2d483d9a3dc5680e83e444cb99061d57d547 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Kristina=20Mart=C5=A1enko?= Date: Tue, 1 Jul 2014 00:50:55 +0300 Subject: [PATCH] staging: serqt_usb2: remove driver MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Remove the driver as it hasn't been cleaned up and it doesn't look like anyone is going to work on it anymore. This can be reverted if someone wants to work to fix the remaining issues the driver has.
