[PATCH 4.19 003/106] mlxsw: spectrum_switchdev: Set PVID correctly during VLAN deletion

[Greg Kroah-Hartman]

4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ido Schimmel <idosch@xxxxxxxxxxxx>

[ Upstream commit 674bed5df4cab8f96d04f7b99608883a48f9226b ]

When a VLAN is deleted from a bridge port we should not change the PVID
unless the deleted VLAN is the PVID.

Fixes: fe9ccc785de5 ("mlxsw: spectrum_switchdev: Don't batch VLAN operations")
