[Tzung-Bi Shih <tzungbi@kernel.org>]

The series adds Kunit tests, refactors, and clean-ups for cros_ec_query_all().

Tzung-Bi Shih (15):
  platform/chrome: cros_ec_commands: fix compile errors
-> Fixes compile errors when including cros_ec_commands.h.

  platform/chrome: cros_ec_proto: add Kunit tests for
    cros_ec_query_all()
-> Adds Kunit tests for cros_ec_query_all().  They are baseline tests
   for the following refactor patches.

  platform/chrome: use macros for passthru indexes
  platform/chrome: cros_ec_proto: assign buffer size from protocol info
-> Refactors.

  platform/chrome: cros_ec_proto: remove redundant NULL check
-> Clean up.

  platform/chrome: cros_ec_proto: use cros_ec_map_error()
-> Changes the internal return code.

  platform/chrome: cros_ec_proto: separate cros_ec_get_proto_info()
  platform/chrome: cros_ec_proto: handle empty payload in getting proto
    info
  platform/chrome: cros_ec_proto: separate
    cros_ec_get_proto_info_legacy()
  platform/chrome: cros_ec_proto: handle empty payload in getting info
    legacy
-> Check if send_command() returns negative integer.
   Call cros_ec_map_error() to see if msg->result isn't EC_RES_SUCCESS.
   Report -EPROTO if send_command() returns 0.

  platform/chrome: cros_ec: don't allocate `din` and `dout` in
    cros_ec_register()
-> Clean up.

  platform/chrome: use krealloc() for `din` and `dout`
-> Replace devm variant to non-devm.

  platform/chrome: cros_ec_proto: don't show MKBP version if unsupported
-> Minor fix up.

  platform/chrome: cros_ec_proto: return 0 on getting version mask
    success
  platform/chrome: cros_ec_proto: return 0 on getting wake mask success
-> Conform to kernel convention: return 0 on success;
   otherwise, negative integers.
