Commit 4334f30e authored by Linus Torvalds's avatar Linus Torvalds

Merge tag 'char-misc-5.7-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char/misc driver fixes from Greg KH:
 "Here are some small driver fixes for 5.7-rc5 that resolve a number of
  minor reported issues:

   - mhi bus driver fixes found as people actually use the code

   - phy driver fixes and compat string additions

   - most driver fix due to link order changing when the core moved out
     of staging

   - mei driver fix

   - interconnect build warning fix

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