[PATCH 2.6] I2C: Drop I2C_DEVNAME and i2c_clientname

From: Jean Delvare
Date: Mon Aug 15 2005 - 12:56:48 EST


Hi all,

I2C_DEVNAME and i2c_clientname were introduced in 2.5.68 [1] to help
media/video driver authors who wanted their code to be compatible with
both Linux 2.4 and 2.6. The cause of the incompatibility has gone since
[2], so I think we can get rid of them, as they tend to make the code
harder to read and longer to preprocess/compile for no more benefit.

I'd hope nobody seriously attempts to keep media/video driver compatible
across Linux trees anymore, BTW.

[1] http://marc.theaimsgroup.com/?l=linux-kernel&m=104930186524598&w=2
[2] http://www.linuxhq.com/kernel/v2.6/0-test3/include/linux/i2c.h

This patch is meant to reach -mm through Greg's i2c tree.

Thanks.
