Subject: [PATCH v2 01/13] serial: 8250_exar: Don't return positive values as error codes
Date: Fri, 3 May 2024 20:15:53 +0300 [thread overview]
Message-ID: <20240503171917.2921250-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20240503171917.2921250-1-andriy.shevchenko@linux.intel.com>
PCI core may return positive codes for the specific errors.
There is a special API to convert them to negative stanrard ones.
Use that API to avoid returning positive values as error codes.
Fixes: f7ce07062988 ("serial: exar: add CTI specific setup code")
