From: Manu Abraham Date: Mon, 20 Oct 2008 21:14:14 +0000 (-0300) Subject: V4L/DVB (9346): Optimization: Enable gate in a symmetric/disciplined way, X-Git-Tag: v2.6.28-rc5~85^2~32 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=3b37a15c2d75585cc0da49b8e69345af91e227ce;p=linux-2.6-omap-h63xx.git V4L/DVB (9346): 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.
