Subject: drm/exynos: remove function convert_to_vm_err_msg
X-Git-Tag: Ubuntu-5.10.0-12.13~14153^2~26^2~10
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=23597e2642ca76883ef533d3e3947b859537fd49;p=mirror_ubuntu-hirsute-kernel.git

drm/exynos: remove function convert_to_vm_err_msg

The convert_to_vm_err_msg is called just once by exynos_drm_gem_fault,
so it's simple not to use the function.
