misc: hmc6352: fix potential Spectre v1

2018-09-12T07:31:00+00:00

val is indirectly controlled by user-space, hence leading to a potential exploitation of the Spectre variant 1 vulnerability. This issue was detected with the help of Smatch: drivers/misc/hmc6352.c:54 compass_store() warn: potential spectre issue 'map' [r] Fix this by sanitizing val before using it to index map Notice that given that speculation windows are large, the policy is to kill the speculation on the first load and not worry if it can be completed with a dependent load/store [1].

misc: hmc6352: constify i2c_device_id

2017-08-28T14:55:49+00:00

i2c_device_id are not supposed to change at runtime. All functions working with i2c_device_id provided by work with const i2c_device_id. So mark the non-const structs as const. Signed-off-by: Arvind Yadav Signed-off-by: Greg Kroah-Hartman

drivers/misc: delete non-required instances of include

2014-02-07T23:10:19+00:00

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

misc: replace strict_strtoul() with kstrtoul()

2013-06-06T19:54:08+00:00

The usage of strict_strtoul() is not preferred, because strict_strtoul() is obsolete. Thus, kstrtoul() should be used. Signed-off-by: Jingoo Han Reviewed-by: Andy Shevchenko Signed-off-by: Greg Kroah-Hartman

MISC: convert drivers/misc/* to use module_i2c_driver()

2012-01-25T00:31:49+00:00

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()

2011-03-23T00:44:10+00:00

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 compass

2010-08-10T03:45:10+00:00

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.
