   4 Subject: MIPS: ath79: drop _machine_restart again
   5
   6 Commit 81424d0ad0d4 ("MIPS: ath79: Use the reset controller to restart
   7 OF machines") removed setup of _machine_restart on OF machines to use
   8 reset handler in reset controller driver.
   9 While removing remnants of non-OF machines in commit 3a77e0d75eed
  10 ("MIPS: ath79: drop machfiles"), this was introduced again, making it
  11 impossible to use additional restart handlers registered through device
  12 tree. Drop setting _machine_restart altogether, and ath79_restart
  13 function, which is no longer used after this.
