Message-Id: <20210112181441.206545-3-sukadev@linux.ibm.com>

Subject: [PATCH net-next v2 2/7] ibmvnic: update reset function prototypes
The reset functions need just the 'reset reason' parameter and not
the ibmvnic_rwi list element. Update the functions so we can simplify
the handling of the ->rwi_list in a follow-on patch.
Fixes: 2770a7984db5 ("ibmvnic: Introduce hard reset recovery")
