[PATCH 2.6.12-rc4 14/15] include/linux/i2c-sysfs.h: i2c sensor_device_attribute and macros

[Yani Ioannou]

[-- Attachment #1: Type: text/plain, Size: 466 bytes --]

This patch creates a new header with a potential standard i2c sensor
attribute type (which simply includes an int representing the sensor
number/index) and the associated macros, SENSOR_DEVICE_ATTR to define
a static attribute and to_sensor_dev_attr to get a
sensor_device_attribute reference from an embedded device_attribute
reference.

Please see the next patch to see how these can be used.

Oops..I caught this simple typo while compile testing the adm1026
patch with everything, but it looks like I forgot to update the patch,
here is the corrected version (just adding the missing '=' ):

[Yani Ioannou]

You will want to start a new thread (change the subject line) since
this post is completely unrelated to the patch it references.

As for your question I'm probably not the best person to ask, about
those topics, but if you are looking for a kernel reference
http://lxr.linux.no/ is invaluable. Linux Device Drivers 3 looks like
a good reference for driver coding too, I just bought it. Greg KH
would certainly recommend it to you since he is a co-author ;-).

Good luck,
Yani
