4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Geert Uytterhoeven <geert@xxxxxxxxxxxxxx>
[ Upstream commit dcec33c1fc4ab63983d93ffb0d82b68fc5775b88 ]
When building with W=1:
arch/m68k/mvme16x/config.c:208:6: warning: no previous prototype for ‘mvme16x_cons_write’ [-Wmissing-prototypes]
208 | void mvme16x_cons_write(struct console *co, const char *str, unsigned count)
| ^~~~~~~~~~~~~~~~~~
Fix this by introducing a new header file "mvme16x.h" for holding the
prototypes of functions implemented in arch/m68k/mvme16x/.
