Subject: PROBLEM: Linux 6.8 build failure in sun ffb driver (regression)

Hi,

Linux 6.8 (and 6.8.1) are failing to build for me:

  LD      .tmp_vmlinux.kallsyms1
sparc64-unknown-linux-gnu-ld: drivers/video/fbdev/ffb.o:(.rodata+0x270): undefined reference to `fb_io_read'
sparc64-unknown-linux-gnu-ld: drivers/video/fbdev/ffb.o:(.rodata+0x278): undefined reference to `fb_io_write'
make[3]: *** [/home/nbowler/misc/linux/scripts/Makefile.vmlinux:37: vmlinux] Error 1

This problem does not occur when building Linux 6.7 which builds successfully.

Kernel .config attached (gzipped).

Please let me know if you need any more info.

Thanks,
  Nick
