Pull driver core update from Greg KH: "Here's the set of driver core patches for 3.19-rc1. They are dominated by the removal of the .owner field in platform drivers. They touch a lot of files, but they are "simple" changes, just removing a line in a structure. Other than that, a few minor driver core and debugfs changes. There are some ath9k patches coming in through this tree that have been acked by the wireless maintainers as they relied on the debugfs changes.

powerpc: Convert power off logic to pm_power_off

2014-11-03T01:12:51+00:00

The generic Linux framework to power off the machine is a function pointer called pm_power_off. The trick about this pointer is that device drivers can potentially implement it rather than board files. Today on powerpc we set pm_power_off to invoke our generic full machine power off logic which then calls ppc_md.power_off to invoke machine specific power off. However, when we want to add a power off GPIO via the "gpio-poweroff" driver, this card house falls apart. That driver only registers itself if pm_power_off is NULL to ensure it doesn't override board specific logic. However, since we always set pm_power_off to the generic power off logic (which will just not power off the machine if no ppc_md.power_off call is implemented), we can't implement power off via the generic GPIO power off driver. To fix this up, let's get rid of the ppc_md.power_off logic and just always use pm_power_off as was intended. Then individual drivers such as the GPIO power off driver can implement power off logic via that function pointer. With this patch set applied and a few patches on top of QEMU that implement a power off GPIO on the virt e500 machine, I can successfully turn off my virtual machine after halt.

powerpc: make of_device_ids const

2014-09-25T13:14:46+00:00

of_device_ids (i.e. compatible strings and the respective data) are not supposed to change at runtime. All functions working with of_device_ids provided by work with const of_device_ids. This allows to mark all struct of_device_id const, too. While touching these line also put the __init annotation at the right position where necessary.
