From 76efb0ba2118c286231dd062bf02b2537cc8738f Mon Sep 17 00:00:00 2001 From: Michael Krufky Date: Mon, 6 Feb 2012 19:40:32 -0300 Subject: [PATCH] [media] xc5000: allow drivers to set desired firmware in xc5000_attach newer versions of the xc5000 silicon require newer firmware while remaining 100% driver compatible. original versions of the xc5000a continue to use the same firmware.
