2014-11-03Merge branch 'platform/remove_owner' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux into driver-core-nextGreg Kroah-Hartman1-1/+0
Remove all .owner fields from platform drivers
2014-10-20rtc: drop owner assignment from platform_driversWolfram Sang1-1/+0
A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>

2014-10-03efi: rtc-efi: Export platform:rtc-efi as module aliasArd Biesheuvel1-0/+1
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.

2014-08-08drivers/rtc/rtc-efi.c: check for invalid data coming back from UEFIJan Beulich1-5/+27
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?

2014-06-06drivers/rtc/rtc-efi.c: avoid subtracting day twice when computing year daysLee, Chun-Yi1-1/+1
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.

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

2012-04-12drivers/rtc/rtc-efi.c: fix section mismatch warningJan Beulich1-1/+0
efi_rtc_init() uses platform_driver_probe(), so there's no need to also set efi_rtc_driver's probe member (as it won't be used anyway). This fixes a modpost section mismatch warning (as efi_rtc_probe() validly is __init).
