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`.
Fixes: cb5164ac43 ("drm/panic: Add a QR code panic screen")

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
