From eebf8d86acf0db974dfaad8e8285f4e12ca488e2 Mon Sep 17 00:00:00 2001 From: Manu Abraham Date: Thu, 18 Jun 2009 04:50:53 -0300 Subject: [PATCH] V4L/DVB (12131): BUGFIX: An incorrect Carrier Recovery Loop optimization table was being loaded for a given chip version. This would cause the optimization in tuning not to be applied and thus a failed expectation, in tuning speed increment. The patch swaps the tables in use. It also fixes a possible one in a million condition where state->dev_ver implies an older Cut (Cut < 2.0, eventhough the driver doesn't attach to any Cut older than 2.0) or even negative (due to a bad I2C bus master driver) for the card combination. Thanks to Mauro Carvalho Chehab for pointing out the issue at large.
