Subject: [PATCH v1 2/2] serial: 8250_pericom: Re-enable higher baud rates
Date: Wed, 17 Nov 2021 16:57:50 +0200 [thread overview]
Message-ID: <20211117145750.43911-3-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20211117145750.43911-1-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.
