From: Patrick Boettcher Date: Tue, 4 Jul 2006 16:47:16 +0000 (-0300) Subject: V4L/DVB (4457): Remove dib3000-common-module X-Git-Tag: v2.6.19-rc1~643^2~103 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=74340b0a8bc60b400c7e5fe4950303aa6f914d16;p=linux-2.6 V4L/DVB (4457): Remove dib3000-common-module removing the dib3000-common-module. The common stuff is not common anymore - it will be only used by the 3000mb-driver. A new 3000mc/p-driver will be added which will share common stuff with dib7000.
