powerpc/rtas: Fix typo of ibm,open-errinjct in RTAS filter
Commit bd59380c5ba4 ("powerpc/rtas: Restrict RTAS requests from userspace")
introduced the following error when invoking the errinjct userspace
tool:
[root@ltcalpine2-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@ltcalpine2-lp5 linux]# errinjct open
RTAS error injection facility open, token = 1
