This patch (as1303) revises the USB Power Management infrastructure to make it compatible with the new driver-model Runtime PM framework: Drivers are no longer allowed to access intf->pm_usage_cnt directly; the PM framework manages its own usage counters. usb_autopm_set_interface() is eliminated, because it directly sets intf->pm_usage_cnt. usb_autopm_enable() and usb_autopm_disable() are eliminated, because they call usb_autopm_set_interface(). usb_autopm_get_interface_no_resume() and usb_autopm_put_interface_no_suspend() are added. They correspond to pm_runtime_get_noresume() and pm_runtime_put_noidle() in the PM framework. The power/level attribute no longer accepts "suspend", only "on" and "auto". The PM framework doesn't allow devices to be forced into a suspended mode. The hub driver contains the only code that violates the new guidelines. It is updated to use the new interface routines instead. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> |
