Below, there is one more line to update:

-/* set dimensions manually if init != 0 since vc_resize()
will fail */
+/* set dimensions manually if init is true since
vc_resize() will fail */

With the above fixed:

[PATCH 19/45] tty: vt: make init parameter of consw::con_init() a bool

[Jiri Slaby (SUSE)]

The 'init' parameter of consw::con_init() is true for the first call of
the hook on a particular console. So make the parameter a bool.

And document the hook.
