include/linux/i2c-sysfs.h: i2c sensor_device_attribute and macros
PATCH 14/15 include/linux/i2c-sysfs.h: i2c sensor_device_attribute and macros
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.

Hi,
I am joined as reseach scholar and going to work in the feild of wireless technology in sensors with use of linux OS. Can someone suggest me good material for tutorial on linux kernel and implementation of wireless technology in linux middleware

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
