Subject: mlxsw: spectrum: Use correct PVID value when removing VLANs
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=06c071f68d8123bef0f152e5d2c7272920597a7e;p=deliverable%2Flinux.git

mlxsw: spectrum: Use correct PVID value when removing VLANs

When removing a range of VLANs in which PVID is a member we should use
the correct PVID value instead of some VLAN in the range.

Also, change two print statements to use 'dev' instead of
'mlxsw_sp_port->dev', as it's already used in other print statements in
the function.
