From 7e520d09f1a4b3da1d09a4540e3f4fa852658a0d Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Sun, 1 Jul 2007 18:37:51 -0300 Subject: [PATCH] V4L/DVB (5815): Cx88: i2c structure templates clean-up Clean up the use of structure templates in cx88-i2c and cx88-vp3054-i2c. For one thing, a real template is supposed to be read-only. And in some cases it's more efficient to initialize the few fields we need individually. This clean-up shrinks cx88-i2c.o by 33% and cx88-vp3054-i2c.o by 49% (x86_64).
