[PATCH on top of 3/3] ACPI / hotplug: Remove unnecessary get_device() and put_device()

Linux 3.12 released .. and no merge window yet .. and 4.0 plans?

I was vacillating whether to do an rc8 or just cut the final 3.12, but since the biggest reason to *not* do a final release was not so much the state of the code, as simply the fact that I'll be traveling with very bad internet connection next week, I didn't really want to delay the release. Sure,

[PATCH 3/3] ACPI / hotplug: Merge device hot-removal routines

From: Rafael J. Wysocki The only substantial difference between acpi_bus_device_eject() and acpi_bus_hot_remove_device() is the get_device() done by the former which is supposed to be done by callers of the latter. However, at least one caller of acpi_bus_hot_remove_device(), which is

[PATCH 1/3] ACPI / scan: Start matching drivers after trying scan handlers

From: Rafael J. Wysocki ACPI scan handlers should always be attached to struct acpi_device objects before any ACPI drivers, but there is a window during which a driver may be attached to a struct acpi_device before checking if there is a matching scan handler. Namely, that will happen if an

[PATCH 2/3] ACPI / hotplug: Refuse to hot-remove all objects with disabled hotplug

From: Rafael J. Wysocki In theory, an ACPI device object may be the parent of another device object whose hotplug is disabled by user space thorugh its scan handler. In that case, the eject operation targeting the parent should fail as though the parent's own hotplug was disabled, but currently
