[stable-kernel][5.15.y][PATCH 4/5] serial: sc16is7xx: remove unused line structure member

[Hui Wang <hui.wang@canonical.com>]

From: Hugo Villeneuve <hvilleneuve@dimonoff.com>

commit 41a308cbedb2a68a6831f0f2e992e296c4b8aff0 upstream.

Now that the driver has been converted to use one regmap per port, the line
structure member is no longer used, so remove it.

Fixes: 3837a0379533 ("serial: sc16is7xx: improve regmap debugfs by using one regmap per port")
