rtc: remove useless DRV_VERSION

2016-05-20T10:33:51+00:00

Many drivers are defining a DRV_VERSION. This is often only used for
MODULE_VERSION and sometimes to print an info message at probe time. This
is kind of pointless as they are all versionned with the kernel anyway.
Also the core will print a message when a new rtc is found.

rtc: ds1742: clean up ds1742_nvram_read()/ds1742_nvram_write()

2015-09-05T11:19:10+00:00

The change removes redundant sysfs binary file boundary checks, since
this task is already done on caller side in fs/sysfs/file.c

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.

drivers/rtc/rtc-ds1742.c: revert "drivers/rtc/rtc-ds1742.c: remove redundant of_match_ptr() helper"

2014-08-08T22:57:19+00:00

Commit 5516f0971793 ("drivers/rtc/rtc-ds1742.c: remove redundant
of_match_ptr() helper") has description as: "'ds1742_rtc_of_match' is
always compiled in.  Hence the helper macro is not needed".

It is not true, of_match_ptr() macro makes of_device_id parameter unused
and this constant is declared with __maybe_unused attribute, so normally
this variable should be discarded by linker.  This patch revers this
commit, since there are no reason to compile of_device_id constant for
non-DT systems.

rtc: rtc-ds1742: make of_device_id array const

2014-06-06T23:08:07+00:00

Make of_device_id array const, because all OF functions handle it as
const.

drivers/rtc/rtc-ds1742.c: remove unused field "rtc" from private structure

2013-09-11T22:58:58+00:00

Private field "rtc" is not used outside "probe", so there is no reason to
keep it.
