commit 5fe251112646d8626818ea90f7af325bab243efa upstream.

commit 498ba2069035 ("HID: logitech-hidpp: Don't restart communication if
not necessary") put restarting communication behind that flag, and this
was apparently necessary on the T651, but the flag was not set for it.

commit 944ee77dc6ec7b0afd8ec70ffc418b238c92f12b upstream.

The hidraw_open() function increments the hidraw device reference
counter. The counter has no dedicated synchronization mechanism,
resulting in a potential data race when concurrently opening a device.

The race is a regression introduced by commit 8590222e4b02 ("HID:
hidraw: Replace hidraw device table mutex with a rwsem"). While
minors_rwsem is intended to protect the hidraw_table itself, by instead
acquiring the lock for writing, the reference counter is also protected.
This is symmetrical to hidraw_release().

commit 9a6c0e28e215535b2938c61ded54603b4e5814c5 upstream.

Code which interacts with timestamps needs to use the ktime_t type
returned by functions like ktime_get. The int type does not offer
enough space to store these values, and attempting to use it is a
recipe for problems. In this particular case, overflows would occur
when calculating/storing timestamps leading to incorrect values being
reported to userspace. In some cases these bad timestamps cause input
handling in userspace to appear hung.

  HID: hidpp: terminate retry loop on success

It seems we forgot the normal case to terminate the retry loop,
making us asking 3 times each command, which is probably a little bit
too much.

And remove the ugly "goto exit" that can be replaced by a simpler "break"

If an attempt at contacting a receiver or a device fails because the
receiver or device never responds, don't restart the communication, only
restart it if the receiver or device answers that it's busy, as originally
intended.

This was the behaviour on communication timeout before commit 586e8fede795
("HID: logitech-hidpp: Retry commands when device is busy").

This fixes some overly long waits in a critical path on boot, when
checking whether the device is connected by getting its HID++ version.

If high bit is set to 1 in ((data[3] & 0x0f << 28), after all arithmetic
operations and integer promotions are done, high bits in
wacom->serial[idx] will be filled with 1s as well.
Avoid this, albeit unlikely, issue by specifying left operand's __u64
