| |
4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johan Hovold <johan@kernel.org>
commit 06fd9ab12b804451b14d538adbf98a57c2d6846b upstream.
Fix activation helper which would return -ETIMEDOUT even if the last retry attempt was successful.
Also change the semantics of the retries variable so that it actually holds the number of retries (rather than tries).
