Remove all .owner fields from platform drivers

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.

efi: rtc-efi: Export platform:rtc-efi as module alias

2014-10-03T17:41:04+00:00

When the rtc-efi driver is built as a module, we already register the
EFI rtc as a platform device if UEFI Runtime Services are enabled.
To wire it up to udev, and let the module be loaded automatically, we
need to export the 'platform:rtc-efi' alias from the module.

drivers/rtc/rtc-efi.c: check for invalid data coming back from UEFI

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

In particular seeing zero in eft->month is problematic, as it results in
-1 (converted to unsigned int, i.e.  yielding 0xffffffff) getting passed
to rtc_year_days(), where the value gets used as an array index
(normally resulting in a crash).  This was observed with the driver
enabled on x86 on some Fujitsu system (with possibly not up to date
firmware, but anyway).

Perhaps efi_read_alarm() should not fail if neither enabled nor pending
are set, but the returned time is invalid?

drivers/rtc/rtc-efi.c: avoid subtracting day twice when computing year days

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

Compared source code of rtc-lib.c::rtc_year_days() with
efirtc.c::rtc_year_days(), found the code in rtc-efi decreases value of
day twice when it computing year days.  rtc-lib.c::rtc_year_days() has
already decrease days and return the year days from 0 to 365.

drivers/rtc/rtc-efi.c: remove empty function

2013-07-03T23:07:56+00:00

After the switch to devm_* functions and the removal of
rtc_device_unregister(), the 'remove' function does not do anything.
Delete it.
