Subject: [PATCH v3 0/2] platform/chrome: cros_ec: improve probing for RWSIG

V2 -> V3:
- Move exiting from `cros_ec_rwsig_continue` if `error_count` exceeds
  `RWSIG_CONTINUE_MAX_ERRORS_IN_ROW` to the `if (rev < 0)` statement when
  `error_count` is incremented.

V1 -> V2:
- Use dev_info instead of dev_warn when cros_ec_rwsig_continue returns
  an error.
- Return immediately from cros_ec_rwsig_continue, if the RWSIG_ACTION
  command fails itself, not SPI transaction.

Dawid Niedzwiecki (2):
  platform/chrome: cros_ec: jump to RW before probing
  platform/chrome: cros_ec_proto: remove unnecessary retries
