Subject: [PATCH] serial: 8250_pci: Fix EXAR feature control register constants
Date: Fri, 3 Feb 2017 14:22:21 +0100 [thread overview]
Message-ID: <59a3d502-970c-3844-d602-12f889928dd7@siemens.com> (raw)
According to the XR17V352 manual, bit 4 is IrDA control and bit 5 for
485. Fortunately, no driver used them so far.
