From a739a7e4c642ebb1ab803fc2c9743aaf1833058b Mon Sep 17 00:00:00 2001 From: Steven Toth Date: Sat, 11 Oct 2008 12:27:06 -0300 Subject: V4L/DVB (9231): cx23885: Define num_frontends as a function of the port This allows some cardcoded functions to be more flexible, and paves the way for any future cards that may have MFE support. Better to add it now when the MFE patches is fresh in peoples mind, rather than 12 months from now when new cards appear.
