The thermal framework implements a netlink notification mechanism to
be used by the userspace to have a thermal configuration discovery,
trip point changes or violation, cooling device changes notifications,
etc...

This library provides a level of abstraction for the thermal netlink
notification allowing the userspace to connect to the notification
mechanism more easily. The library is callback oriented.

when using hierarchical interrupt domains using "interrupts" property

With the new OS handshake introduced by commit: "c7ff2976 ("thermal:
int340x: Update OS policy capability handshake")", the "enabled" thermal
zone mode doesn't work in the same way as previously.

The "enabled" mode fails with -EINVAL when the new handshake is used.

To address this issue, when the new OS UUID mask is set:

 - When the mode is "enabled", return 0 as the firmware already has the
   latest policy mask.

 - When the mode is "disabled", update the firmware with the UUID mask
   of zero.

This way, the firmware can take over the thermal control.

Also reset the OS UUID mask, which allows user space to update with new
set of policies.

Interrupt handler bad_flp_intr() may cause a UAF on the recently freed
request just to increment the error count.  There's no point keeping
that one in the request anyway, and since the interrupt handler uses a
static pointer to the error which cannot be kept in sync with the
pending request, better make it use a static error counter that's reset
for each new request.  This reset now happens when entering
redo_fd_request() for a new request via set_next_request().

One initial concern about a single error counter was that errors on one
floppy drive could be reported on another one, but this problem is not
real given that the driver uses a single drive at a time, as that
PC-compatible controllers also have this limitation by using shared
signals.  As such the error count is always for the "current" drive.
