From 1b750d09fe362a231b9a25ed75e61f642f24c880 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Wed, 21 Dec 2011 07:13:50 -0300 Subject: [PATCH] [media] mxl5005s: fix: don't discard bandwidth changes There is a bug on mxl5005s logic: when the bandwidth changes, but using the same delivery system, the code discard the set_params() reconfiguration request. This was happening because, in the previous coding, the bandwidth calculus were after the check for delivery system changes. The previous patch changed the logic to estimate the bandwidth to happend together with the changes at the delivery system. So, with a one-statement change, it is possible to make the tuner to reconfigure, in order to adjust to bandwidth changes. this will likely fix issues on countries that use 7MHz/8MHz DVB-T channels.
