From 723dbc0b30db9de883635895dd341fbeb6f388fe Mon Sep 17 00:00:00 2001 From: Manu Abraham Date: Tue, 21 Oct 2008 01:14:14 +0400 Subject: Optimization: Enable gate in a symmetric/disciplined way, rather than implementing different ways leading to confusion. This allows multiple gate_enable/disable's in the tuner_read/write functions, thereby lesser number of I/O operations throughout, eventually leading to better results. As a side effect demods that detect the STOP bit for auto closing of the gate can be avoided, thereby a very minimal gain in disabling the auto detect feature as well. Improves readability on the device control.
