From b287db119edb92548b53f63f05fd593c43cba200 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sat, 5 Feb 2011 09:25:02 -0300 Subject: [PATCH] [media] se401: remove last V4L1 driver This driver is for obsolete hardware that the old maintainer didn't care (or not have the hardware anymore), and that no other developer could find any hardware to buy. The V4L1 API is no longer supported, and since nobody stepped in to convert them to V4L2 the decision was made to remove them.
