powerpc/pseries: fix possible memory leak in ibmebus_bus_init() If device_register() returns error in ibmebus_bus_init(), name of kobject which is allocated in dev_set_name() called in device_add() is leaked. As comment of device_add() says, it should call put_device() to drop the reference count that was set in device_initialize() when it fails, so the name can be freed in kobject_cleanup().

powerpc: Explicitly include correct DT includes The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

of: device: make of_device_uevent_modalias() take a const device * of_device_uevent_modalias() does not modify the device pointer passed to it, so mark it constant. In order to properly do this, a number of busses need to have a modalias function added as they were attempting to just point to of_device_uevent_modalias instead of their bus-specific modalias function. This is fine except if the prototype for a bus and device type modalias function diverges and then problems could happen. To prevent all of that, just wrap the call to of_device_uevent_modalias() directly for each bus and device type individually.

bus: Make remove callback return void The driver core ignores the return value of this callback because there is only little it can do when a device disappears. This is the final bit of a long lasting cleanup quest where several buses were converted to also return void from their remove callback. Additionally some resource leaks were fixed that were caused by drivers returning an error code in the expectation that the driver won't go away. With struct bus_type::remove returning void it's prevented that newly implemented buses return an ignored error code and so don't anticipate wrong expectations for driver authors.

This is mostly fine, but it can result in some nuisance errors in dmesg when booting on PowerNV on some OSes, e.g. [ 2.984439] synth uevent: /devices/vio: failed to send uevent [ 2.984442] vio vio: uevent: failed to send synthetic uevent [ 17.968551] synth uevent: /devices/vio: failed to send uevent [ 17.968554] vio vio: uevent: failed to send synthetic uevent We don't see anything similar for the ibmebus because that depends on !CONFIG_LITTLE_ENDIAN.

bus_find_device: Unify the match callback with class_find_device There is an arbitrary difference between the prototypes of bus_find_device() and class_find_device() preventing their callers from passing the same pair of data and match() arguments to both of them, which is the const qualifier used in the prototype of class_find_device(). If that qualifier is also used in the bus_find_device() prototype, it will be possible to pass the same match() callback function to both bus_find_device() and class_find_device(), which will allow some optimizations to be made in order to avoid code duplication going forward. Also with that, constify the "data" parameter as it is passed as a const to the match function. For this reason, change the prototype of bus_find_device() to match the prototype of class_find_device() and adjust its callers to use the const qualifier in accordance with the new prototype of it.

Replace macros for the basic permission flags (user/group/other read/write/execute) with numeric constants instead, across the whole powerpc tree. Introducing a significant number of changes across the tree for no runtime benefit isn't exactly desirable, but so long as these macros are still used in the tree people will keep sending patches that add them. Not only are they hard to parse at a glance, there are multiple ways of coming to the same value (as you can see with 0444 and 0644 in this patch) which hurts readability.

powerpc/pseries/ibmebus: Remove legacy suspend/resume support There are no ibmebus driver that make use of legacy suspend/resume. This patch removes the support for it from ibmebus framework, new ibmebus driver (as unlikely as they are) wanting to use suspend/resume should use dev_pm_ops. Since there aren't any special bus specific things to do during suspend/resume and since the PM core will automatically fallback directly to using the device's PM ops if no bus PM ops are specified there is no need to have any special ibmebus PM ops at all.
