[PATCH v3 0/3] Improve error handling in Rockchip Inno USB 2.0 PHY driver

[Dragan Simic]

This is a small series that improves error handling in the probe path
of the Rockchip Innosilicon USB 2.0 PHY driver, by returning the actual
error code in one place and by using dev_err_probe() properly in multiple
places.  It also performs a bunch of small, rather trivial code cleanups,
to make the code neater and a bit easier to read.

Changes in v3:
  - Collected Reviewed-by tags from Heiko for patches 1/3 and 2/3
  - Brought back one empty line as a separator of dissimilar operations
    in patch 1/3, as suggested by Heiko [2]
  - Dropped one backward conversion of dev_err_probe() to dev_err() in
    patch 3/3, as suggested by Heiko, [3] and adjusted the summary and
    description of patch 3/3 accordingly

Changes in v2:
  - Expanded into a small series, after a suggestion from Heiko [1] to
    use dev_err_probe(), because it all happens in the probe path
