Subject[PATCH v3 1/5] serial: sc16is7xx: unconditionally clear line bit in sc16is7xx_remove()
From: Hugo Villeneuve <hvilleneuve@dimonoff.com>

There is no need to check for previous port registration in
sc16is7xx_remove() because if sc16is7xx_probe() succeeded, we are
guaranteed to have successfully registered both ports. We can thus
unconditionally clear the line allocation bit in sc16is7xx_lines.
