Under `CONFIG_DRM_PANIC_SCREEN_QR_CODE=y`, zlib is used:

    ld.lld: error: undefined symbol: zlib_deflate_workspacesize
    >>> referenced by drm_panic.c
    >>>               drivers/gpu/drm/drm_panic.o:(drm_panic_qr_init) in archive vmlinux.a

Thus select `CONFIG_ZLIB_DEFLATE`.

Hi, good catch, yes it should select the zlib deflate.
