[PATCH] tty: hvc: make symbol 'hvc_udbg_dev' static
From: Yu Kuai
Date: Wed Apr 07 2021 - 08:50:39 EST
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.
