[PATCH -next] tty: hvc: make hvc_rtas_dev static

From: ruanjinjie
Date: Wed Oct 19 2022 - 02:47:57 EST


The symbol is not used outside of the file, so mark it static.

Fixes the following warning:

drivers/tty/hvc/hvc_rtas.c:29:19: warning: symbol 'hvc_rtas_dev' was
not declared. Should it be static?
