Getting a report (e.g. feature report) from a device requires us to send
a request indicating which report we want to retrieve and then waiting
for the corresponding response containing that report. We already
provide the response structure to the request call, but the request
isn't marked as a request that expects a response. Thus the request
returns before we receive the response and the response buffer indicates
a zero length response due to that.
This essentially means that the get-report calls are broken and will
always indicate that a report of length zero has been read.
Fix this by appropriately marking the request.

This commit fixes a freeze on insertion of a Guitar Hero Live PS3/WiiU
USB dongle. Indeed, with the current implementation, inserting one of
those USB dongles will lead to a hard freeze. I apologize for not
catching this earlier, it didn't occur on my old laptop.
While the issue was isolated to memory alloc/free, I could not figure
out why it causes a freeze. So this patch fixes this issue by
simplifying memory allocation and usage.
We remind that for the dongle to work properly, a control URB needs to
be sent periodically. We used to alloc/free the URB each time this URB
needed to be sent.
With this patch, the memory for the URB is allocated on the probe, reused
for as long as the dongle is plugged in, and freed once the dongle is
unplugged.

Different platforms have different DMA capability, on most of
platforms, DMA support cache snooping. But few platforms,
such as ElkhartLake (EHL), don't support cache snooping
which requires cache flush from driver.
So add a hardware level callback to let ishtp driver know if cache
flush is needed.
As most of platform support cache snooping, so driver will not
do cache flush by default, until platform implements this callback
and return true explicitly.

There is no need to use a quirk and then return -ENODEV from the

The hid-multitouch hiddev has a group of HID_GROUP_MULTITOUCH_WIN_8,

By default 27 MHz Logitech keyboards send the keypresses to the receiver
in plain text. Logitech's Windows "Keyboard and Mouse settings" tool allows
configuring encryption for the keyboard wireless link.
Now there also is a Linux tool for setting this up:
https://gitlab.freedesktop.org/jwrdegoede/logitech-27mhz-keyboard-encryption-setup
Once a keyboard is paired in encrypted mode, it will no longer work with
any receiver other then the receiver it was paired with.
If a user accidentally tries to pair another keyboard with the receiver
with which a keyboard has been paired in encrypted mode, then the receiver
looses the encryption key and the originally paired keyboard will no longer
work with either that receiver, or another receiver until the keyboard's
encryption key is rewritten by another encrypted mode pairing using the
tool. Or until it is reset by following a special reset procedure.
This commit adds 3 new log messages related to 27 MHz keyboard link
encryption to the Logitech dj / hidpp drivers:
1. An info level message when keyboard encryption is being used
2. A warning message when keyboard encryption is not used
3. An error message when the encryption key has been lost and the
keyboard will not work because of this
Messages 2. and 3. contain a link to the userspace tool to setup the
encryption. The linked page also contains instructions to clear the key
(without needing the tool) to help a user recover from the keyboard not
working in case 3.
