Subject: [PATCH v1 1/1] serial: max3100: Convert to_max3100_port() to be static inline
Date: Wed, 10 Apr 2024 17:11:35 +0300
Message-ID: <20240410141135.1378948-1-andriy.shevchenko@linux.intel.com>
Precedence: bulk
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

As Jiri rightfully pointed out the current to_max3100_port() macro
implementation is fragile in a sense that it expects the variable
name to be port, otherwise it blow up the build.

Change this to be static inline to prevent bad compilation.
