commit 45dba8011efac11a2f360383221b541f5ea53ce5 upstream.
If get_1284_register() fails, the usb device reference count is
incorrect and needs to be properly dropped before returning. That will
happen when the kref is dropped in the call to destroy_priv(), so jump
to that error path instead of returning directly.

commit 7a875c09899ba0404844abfd8f0d54cdc481c151 upstream.
The bbu member of the descriptor must be set to the value
standing for uninitialized values before the URB whose
completion handler sets bbu is submitted. Otherwise there is
a window during which probing can overwrite already retrieved
data.

usb: Remove redundant pm_runtime_mark_last_busy() calls2025-11-21T14:11:53+00:00Sakari Ailussakari.ailus@linux.intel.com2025-11-11T09:51:17+00:00urn:sha1:8d3c283ef80950532500f017a80a00a83e8cce0f
pm_runtime_put_autosuspend(), pm_runtime_put_sync_autosuspend(),
pm_runtime_autosuspend() and pm_request_autosuspend() now include a call
to pm_runtime_mark_last_busy(). Remove the now-reduntant explicit call to
pm_runtime_mark_last_busy().

The Intel USBIO driver is x86 only, other architectures have ACPI
so add an appropriate depenecy plus compile test.

Add a driver for the Intel USBIO USB IO-expander used by the MIPI cameras
on various new (Meteor Lake and later) Intel laptops.
This is an USB bridge driver which adds auxbus child devices for the GPIO,
I2C and SPI functions of the USBIO chip and which exports IO-functions for
the drivers for the auxbus child devices to communicate with the USBIO
device's firmware.
