From 63bbdb4ea02b17f929fa4f5c536357183eba9639 Mon Sep 17 00:00:00 2001 From: Yu Kuai Date: Wed, 7 Apr 2021 20:58:26 +0800 Subject: [PATCH] tty: hvc: make symbol 'hvc_udbg_dev' static The sparse tool complains as follows: drivers/tty/hvc/hvc_udbg.c:20:19: warning: symbol 'hvc_udbg_dev' was not declared. Should it be static? This symbol is not used outside of hvc_udbg.c, so this commit marks it static.
