4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Heiner Kallweit <hkallweit1@xxxxxxxxx>
[ Upstream commit d25ed413d5e51644e18f66e34eec049f17a7abcb ]
When debugging an issue I found implausible values in state->pause.
Reason in that state->pause isn't initialized and later only single
bits are changed. Also the struct itself isn't initialized in
phylink_resolve(). So better initialize state->pause and other
not yet initialized fields.
v2:
- use right function name in subject
v3:
- initialize additional fields
Fixes: 9525ae83959b ("phylink: add phylink infrastructure")
