| |
When booting a multi-platform m68k kernel on a non-Amiga with "console=ttyS0" on the kernel command line, it crashes with:
Unable to handle kernel access at virtual address 81dff01c Oops: 00000000 PC: [<001e09a8>] serial_console_write+0xc/0x70
Add the missing platform check to amiserial_console_init() to fix this.
