* MISC: convert drivers/misc/* to use module_i2c_driver()Axel Lin2012-01-241-12/+1
| | | | | | | | | | | | | | | | | | | | | This patch converts the drivers in drivers/misc/* to use the module_i2c_driver() macro which makes the code smaller and a bit simpler.

* drivers/misc/hmc6352.c: fix wrong return value checking for i2c_master_recv()Axel Lin2011-03-221-2/+2
| | | | | | | | | | | | | i2c_master_recv() returns negative errno, or else the number of bytes read. Thus i2c_master_recv(client, i2c_data, 2) returns 2 instead of 1 in success case.

* hmc6352: add driver for the HMC6352 compassKalhan Trisal2010-08-091-0/+166
This driver will report the heading values in degrees to the sysfs interface. The values returned are headings . e.g. 245.6 Alan: Cleanups requested now all folded in and a sysfs description to keep Andrew happy. The sysfs description now resembles hwmon.
