Subject: i2c: Drivers stop using the redundant client list
X-Git-Tag: v2.6.25-rc1~1186
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=961f80f9c0c0f7c45d7818f9c9969dfaa9e4463d;p=linux-2.6

i2c: Drivers stop using the redundant client list

The redundant i2c client list maintained by i2c-core is going away
soon, so drivers should stop using it now. Instead, they can use the
standard iterator provided by the device driver model
(device_for_each_child).
