Subject: tty: hvc: make symbol 'hvc_udbg_dev' static
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=63bbdb4ea02b17f929fa4f5c536357183eba9639;p=linux.git

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.
