Subject: serial: 8250: Make symbol 'brcmuart_debugfs_root' static
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b0b07762bfa41b292c45f78e0b37870e6c30bb27;p=linux.git

serial: 8250: Make symbol 'brcmuart_debugfs_root' static

symbol 'brcmuart_debugfs_root' is not used outside of 8250_bcm7271.c,
so this commit marks it static.
