rtc: constify rtc_class_ops structures

2016-09-01T23:24:06+00:00

Check for rtc_class_ops structures that are only passed to
devm_rtc_device_register, rtc_device_register,
platform_device_register_data, all of which declare the corresponding
parameter as const.  Declare rtc_class_ops structures that have these
properties as const.

The semantic patch that makes this change is as follows:

rtc: Fix module autoload for OF platform drivers

2015-09-05T17:37:22+00:00

These platform drivers have a OF device ID table but the OF module
alias information is not created so module autoloading won't work.

rtc: drop owner assignment from platform_drivers

2014-10-20T14:21:31+00:00

A platform_driver does not need to set an owner, it will be populated by the
driver core.

rtc: rtc-coh901331: use devm_ioremap_resource()

2014-04-03T23:21:18+00:00

Use devm_ioremap_resource() in order to make the code simpler, and
remove redundant return value check of platform_get_resource() because
the value is checked by devm_ioremap_resource().

rtc: rtc-coh901331: use platform_{get,set}_drvdata()

2013-07-03T23:07:55+00:00

Use the wrapper functions for getting and setting the driver data using
platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev,
so we can directly pass a struct platform_device.

rtc: rtc-coh901331: remove unnecessary platform_set_drvdata()

2013-07-03T23:07:49+00:00

The driver core clears the driver data to NULL after device_release or
on probe failure, since commit 0998d063100 ("device-core: Ensure drvdata
= NULL when no driver is bound").  Thus, it is not needed to manually
clear the device driver data to NULL.
