Hi Greg, After merging the tty tree, today's linux-next build (x86_64 allmodconfig) failed like this:
drivers/usb/misc/sisusbvga/sisusb_con.c: In function 'sisusb_console_init':
drivers/usb/misc/sisusbvga/sisusb_con.c:1493:2: error: implicit declaration of
function 'take_over_console' [-Werror=implicit-function-declaration]
ret = take_over_console(&sisusb_con, first - 1, last - 1, 0);

Caused by commit dc9641895abb ("vt: delete unneeded functions
register_con_driver|take_over_console"). Grep is your friend! There is
more to clean up here:

register_con_driver() will just add the driver to

implies, will also take over (or
