[patch] 2.5.25 I2C driver id and Config updates

[Albert Cranford]

[-- Attachment #1: Type: text/plain, Size: 266 bytes --]

Hello Linus,
Could you please apply these 3 patches toward 2.5.26.
They include Config.in updates, additions in i2c-id.h
for "Video for Linux" and a compatibility fix for
i2c-algo-bit.c


Thanks,
Albert

What is the purpose of this patch? I can't see it making any difference
(at least ot in menuconfig).
