char: misc: deallocate static minor in error path

commit 6d991f569c5ef6eaeadf1238df2c36e3975233ad upstream.

When creating sysfs files fail, the allocated minor must be freed such that
it can be later reused. That is specially harmful for static minor numbers,
since those would always fail to register later on.

misc: misc_minor_alloc to use ida for all dynamic/misc dynamic minors

commit 6d04d2b554b14ae6c428a9c60b6c85f1e5c89f68 upstream.

misc_minor_alloc was allocating id using ida for minor only in case of
MISC_DYNAMIC_MINOR but misc_minor_free was always freeing ids
using ida_free causing a mismatch and following warn:
> > WARNING: CPU: 0 PID: 159 at lib/idr.c:525 ida_free+0x3e0/0x41f
> > ida_free called for id=127 which is not allocated.

> > [<605acb82>] misc_deregister+0x171/0x1b3

misc_minor_alloc is changed to allocate id from ida for all minors
falling in the range of dynamic/ misc dynamic minors

Pull driver core updates from Greg KH:
"Here is the large set of driver core changes for 6.4-rc1.

Once again, a busy development cycle, with lots of changes happening
in the driver core in the quest to be able to move "struct bus" and
"struct class" into read-only memory, a task now complete with these
changes.

This will make the future rust interactions with the driver core more
"provably correct" as well as providing more obvious lifetime rules
for all busses and classes in the kernel.

The changes required for this did touch many individual classes and
busses as many callbacks were changed to take const * parameters
instead. All of these changes have been submitted to the various
subsystem maintainers, giving them plenty of time to review, and most
of them actually did so.

Other than those changes, included in here are a small set of other
things:

- kobject logging improvements

- cacheinfo improvements and updates

- obligatory fw_devlink updates and fixes

- documentation updates

- device property cleanups and const * changes

- firwmare loader dependency fixes.

All of these have been in linux-next for a while with no reported
problems"
