Subject: [PATCH v2 2/3] serial: 8250_pericom: Re-enable higher baud rates
Date: Mon, 22 Nov 2021 15:35:11 +0200	[thread overview]
Message-ID: <20211122133512.8947-3-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20211122133512.8947-1-andriy.shevchenko@linux.intel.com>

From: Jay Dolan <jay.dolan@accesio.com>

Add UPF_MAGIC_MULTIPLIER to the port flags since there is now
range checking in serial8250_get_baud_rate() in 8250_port.c.
