rtc: remove useless DRV_VERSION

2016-05-20T10:33:51Z

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. Signed-off-by: Alexandre Belloni

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

2015-09-05T11:19:10Z

The change removes redundant sysfs binary file boundary checks, since this task is already done on caller side in fs/sysfs/file.c Signed-off-by: Vladimir Zapolskiy Signed-off-by: Alexandre Belloni

rtc: drop owner assignment from platform_drivers

2014-10-20T14:21:31Z

A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang

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

2014-08-08T22:57:19Z

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.

drivers/rtc/rtc-ds1742.c: report to RTC core if retrieved time is invalid

2013-09-11T22:58:58Z

Let RTC core decide if the retrieved time is invalid, instead of processing errors in the driver. Signed-off-by: Alexander Shiyan Cc: Jingoo Han Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

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

2013-09-11T22:58:58Z

Private field "rtc" is not used outside "probe", so there is no reason to keep it. Signed-off-by: Alexander Shiyan Cc: Jingoo Han Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
