[PATCH 1/3] Input: adxl34x - use device core to create driver-specific device attributes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Instead of creating driver-specific device attributes with
sysfs_create_group() have device core do this by setting up dev_groups
pointer in the driver structure.
