From 4cd4475effd8fb6fd021fc7c881b4aa74480fa9e Mon Sep 17 00:00:00 2001 From: Maksim Salau Date: Mon, 24 Apr 2017 12:59:53 +0300 Subject: [PATCH] USB: serial: upd78f0730: make constants static Some local constants don't change from call to call and are good candidates to become static. This will prevent copying of these constants to stack during runtime.
