From: Jean Delvare Date: Sat, 2 Apr 2005 18:04:41 +0000 (+0200) Subject: [PATCH] I2C: Merge unused address lists in some video drivers X-Git-Tag: v2.6.13-rc1~68^2~540^2~57 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=68cc9d0b714d7d533c0cfc257a62f7f7f4f22a11;p=linux-2.6 [PATCH] I2C: Merge unused address lists in some video drivers On top of my previous patch which removes the use of address ranges in video i2c drivers, this one can save an additional few bytes of memory. Most of these drivers which do not use I2C_CLIENT_INSMOD initialize the unused address lists in a less than optimal way. This patch simply optimizes this, by using a single one-element list instead of 3 different lists with two elements each. This saves an average 63 bytes on these drivers.
