Subject: [PATCH 4.19 303/346] powerpc/rtas: Fix typo of ibm,open-errinjct in RTAS filter

From: Tyrel Datwyler <tyreld@...ux.ibm.com>

commit f10881a46f8914428110d110140a455c66bdf27b upstream.

Commit bd59380c5ba4 ("powerpc/rtas: Restrict RTAS requests from userspace")
introduced the following error when invoking the errinjct userspace
tool:

  [root@...alpine2-lp5 librtas]# errinjct open
  [327884.071171] sys_rtas: RTAS call blocked - exploit attempt?
  [327884.071186] sys_rtas: token=0x26, nargs=0 (called by errinjct)
  errinjct: Could not open RTAS error injection facility
  errinjct: librtas: open: Unexpected I/O error

The entry for ibm,open-errinjct in rtas_filter array has a typo where
the "j" is omitted in the rtas call name. After fixing this typo the
errinjct tool functions again as expected.

  [root@...alpine2-lp5 linux]# errinjct open
  RTAS error injection facility open, token = 1
