2017-08-28misc: hmc6352: constify i2c_device_idArvind Yadav
i2c_device_id are not supposed to change at runtime. All functions working with i2c_device_id provided by <linux/i2c.h> work with const i2c_device_id. So mark the non-const structs as const.

2014-02-07drivers/misc: delete non-required instances of include <linux/init.h>Paul Gortmaker
None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

2013-06-06misc: replace strict_strtoul() with kstrtoul()Jingoo Han
The usage of strict_strtoul() is not preferred, because strict_strtoul() is obsolete. Thus, kstrtoul() should be used. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Reviewed-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-01-24MISC: convert drivers/misc/* to use module_i2c_driver()Axel Lin
This patch converts the drivers in drivers/misc/* to use the module_i2c_driver() macro which makes the code smaller and a bit simpler.

2011-03-22drivers/misc/hmc6352.c: fix wrong return value checking for i2c_master_recv()Axel Lin
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.

2010-08-09hmc6352: add driver for the HMC6352 compassKalhan Trisal
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.
