Pull char/misc driver fixes from Greg KH:
 "Here are three tiny driver fixes for 6.0-rc7.  They include:

   - phy driver reset bugfix

   - fpga memleak bugfix

   - counter irq config bugfix

  The first two have been in linux-next for a while, the last one has
  only been added to my tree in the past few days, but was in linux-next
  under a different commit id. I couldn't pull directly from the counter
  tree due to some gpg key propagation issue, so I took the commit
  directly from email instead"

* tag 'char-misc-6.0-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc:
  counter: 104-quad-8: Fix skipped IRQ lines during events configuration
  fpga: m10bmc-sec: Fix possible memory leak of flash_buf
  phy: marvell: phy-mvebu-a3700-comphy: Remove broken reset support
