Subject: [PATCH 0/4] char: misc: improve test and dynamic allocation

These apply on top of commit 6d04d2b554b1 ("misc: misc_minor_alloc to use
ida for all dynamic/misc dynamic minors") and commit 37df9043329b
("misc:minor basic kunit tests"), both at char-misc-next.

The tests are written in order to detect regressions around the bug fixed
by commit 6d04d2b554b1 ("misc: misc_minor_alloc to use ida for all
dynamic/misc dynamic minors") and the followup fixing commits "char: misc:
restrict the dynamic range to exclude reserved minors" and "char: misc:
deallocate static minor in error path".

  char: misc: improve testing Kconfig description
  char: misc: add test cases
  char: misc: restrict the dynamic range to exclude reserved minors
  char: misc: deallocate static minor in error path
