usb: Allow drivers to enable USB autosuspend on a per-device basis
|
||||
|
||||
USB autosuspend is currently only enabled by default for hubs. On other
|
||||
hardware the decision is made by userspace. This is unnecessary in cases
|
||||
where we know that the hardware supports autosuspend, so this patch adds
|
||||
a function to allow drivers to enable it at probe time.
