Merge patch series "can: etas_es58x: clean-up of new GCC W=1 and old checkpatch warnings"

Vincent Mailhol <mailhol.vincent@wanadoo.fr> says:

The kernel recently added new warnings, one of which triggers a known
false positive on the etas_es58x module. In an effort to keep
es58x_etas free of any W=12 (excluding those produced by foreign
headers), add a workaround to silence it.

While at it, this series also fix a checkpatch warning which I knew
existed for a long time but was too lazy to tackle.

v2 -> v3:
* if the parsing of one of the version/revision numbers fail,
  es58x_parse_product_info() immediately returns. If this occurs early,
  the other version/revision numbers would still be set to zero (which
  is now considered a valid version number). Set the version and
  revision to an invalid number before starting the parsing so that
  everything is set even if an early return occurs.

v1 -> v2:
* v1 had two different check logics for the version numbers:
  - check that none of the sub-version number are zero to make sure
    the parsing succeeded
  - check that all of the sub-version number fit the expected digit
    range to please GCC.

  v2 simplifies things by merging those two logics together.
