If you fix the issue, kindly add following tag as appropriate
Reported-by: kernel test robot <lkp@xxxxxxxxx>

All errors (new ones prefixed by >>):

hppa64-linux-ld: drivers/firmware/sysfb.o: in function `sysfb_init':
(.init.text+0x8): undefined reference to `screen_info'
hppa64-linux-ld: (.init.text+0xc): undefined reference to `screen_info'

This could be related to the recent rework of the system-framebuffer code. I think the config has to be updated to select SYSFB and SYSFB_SIMPLEFB. [1]
