Thanks for your reply. I will communicate with member of dri-devel further.
I tried to reproduce this issue on master branch and there was no link error:
...
CC arch/x86/boot/compressed/efi.o
AS arch/x86/boot/compressed/efi_mixed.o
CC arch/x86/boot/compressed/misc.o
GZIP arch/x86/boot/compressed/vmlinux.bin.gz
MKPIGGY arch/x86/boot/compressed/piggy.S
AS arch/x86/boot/compressed/piggy.o
LD arch/x86/boot/compressed/vmlinux
ZOFFSET arch/x86/boot/zoffset.h
OBJCOPY arch/x86/boot/vmlinux.bin
AS arch/x86/boot/header.o
LD arch/x86/boot/setup.elf
OBJCOPY arch/x86/boot/setup.bin
BUILD arch/x86/boot/bzImage
Kernel: arch/x86/boot/bzImage is ready (#1)
$ cat .config | grep 'CONFIG_DRM_KMS\|CONFIG_FB\b\|FBDEV_EMUL'
CONFIG_DRM_KMS_HELPER=y
CONFIG_DRM_FBDEV_EMULATION=y
CONFIG_FB=m
$
In the attachments you can find two ".config".
kernel_config_515y_failed is used on branch 5.15.y (tag 5.15.157) and
kernel_config_master_succeed is what I used for master branch.
