staging: usbip: Don't leak struct file.
usbip takes a reference on a struct file which is passed in via
sysfs. Previously, this reference was never cleaned up, although
the socket it referred to was.
This patch drops the corresponding reference (found with the
socket's ->file backpointer) instead of just closing the socket.

staging: comedi: always set hw_dev during auto-config
Auto-configuration (auto-attachment) of USB and PCI comedi devices all
goes through `comedi_auto_config_helper()`. That is a good place to set
the comedi device's `hw_dev` pointer to the hardware `struct device` via
a call to `comedi_set_hw_dev(comedi_device, hardware_device)` as it may
obviate the need for the low-level comedi driver to make this call.

The remaining comedi drivers that still have a devpriv macro
are all pretty straight forward for removing the devpriv
macro.
This macro relies on a local variable having a specific name.
Remove its use by replacing it with a local variable where
used.
The inline function alloc_private(), used to kzalloc the
dev->private memory, returns non-zero if there is an error.
Fix all the alloc_private() calls accordingly and remove any
kernel messages or obvious comments that still exist in the
drivers. Leave a comment in the skel driver.

This macro relies on a local variable having a specific name.
Remove its use in all the files by replacing it with a local

Some of the functions in ni_mio_common.c don't always use the
devpriv variable due to differences in how the low-level i/o
is handled by the driver. Tag the variable in those functions
with __maybe_unused to avoid compile warnings.

Previously we registered a notifier block to inform us of any framebuffer

Turns out that the backlight code registers a notifier block as well
and calls the update_status hook, so we can just use that to put the DCON
to sleep. For those status updates where the blanking isn't changed,
dcon_sleep will do nothing.
