[PATCHv4 0/4] OPAL patches

[Jon Derrick]

Just a couple of fixes for sed-opal to prevent faulty firmware from
allowing us to go off in the weeds, and a helper to remove some
duplicate code.

v3->v4:
uses IS_ERR since tok is embedded in the response buffer and cannot be NULL

v2->v3:
corrected the bad calculation on the response parser check and changed
it to only check the subpacket length

v1->v2:
left tok->len as a size_t
got everyone important on the same email thread

Jon Derrick (4):
  block/sed: Use ssize_t on atom parsers to return errors
  block/sed: Add helper to qualify response tokens
  block/sed: Check received header lengths
  MAINTAINERS: Remove powerpc's opal match
