2014-02-08drivers/misc: delete non-required instances of include <linux/init.h>Paul Gortmaker1-1/+0
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 Han1-2/+3
The usage of strict_strtoul() is not preferred, because strict_strtoul() is obsolete.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>
2013-04-11misc: apds9802als: Fix suspend/resumeLars-Peter Clausen1-21/+4
The apds9802als driver implements runtime pm and at the same time uses the legacy pm callbacks for suspend and resume. This does not work since the i2c core wont look at the legacy pm callbacks if a driver has the 'pm' field set. This patch fixes it by moving over to dev_pm_ops for suspend/resume as well. Since both runtime pm and suspend/resume behave the same way this can easily be done using the UNIVERSAL_DEV_PM_OPS macro.

2012-11-16misc: apds9802als: Fix the logic checking timeout in als_wait_for_data_ready()Axel Lin1-1/+1
In the case of timeout waiting for data ready, the retry variable is -1. This also fixes a bug: current code returns -ETIMEDOUT if latest retry success ( which means retry is 0 when exiting the while loop ).

2012-01-25MISC: convert drivers/misc/* to use module_i2c_driver()Axel Lin1-11/+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.

resume()/probe() is handled Put the device into runtime suspend after resume()/probe() is handled by the PM core and the device core code. No need to manually add them in each single driver.
