Commit 399516ab0fee ("MAINTAINERS: Add a bunch of legacy (UMS) DRM drivers")
marked mga driver obsolete 7 years ago.
And the mesa UMD of this drm driver already in deprecated list
in the link: https://docs.mesa3d.org/systems.html
Matrox-->driver/gpu/drm/mga

It's time to remove this driver.

drm/mga/mga_ioc32: Use struct_group() for memcpy() region 2021-09-25T15:20:48+00:00 Kees Cook keescook@chromium.org 2021-05-25T06:55:11+00:00 10579b75e02362809e8db610f3160f520607b395 In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memcpy(), memmove(), and memset(), avoid intentionally writing across neighboring fields. Use struct_group() in struct drm32_mga_init around members chipset, sgram, maccess, fb_cpp, front_offset, front_pitch, back_offset, back_pitch, depth_cpp, depth_offset, depth_pitch, texture_offset, and texture_size, so they can be referenced together. This will allow memcpy() and sizeof() to more easily reason about sizes, improve readability, and avoid future warnings about writing beyond the end of chipset. "pahole" shows no size nor member offset changes to struct drm32_mga_init. "objdump -d" shows no meaningful object code changes (i.e. only source line number induced differences and optimizations). Note that since this is a UAPI header, __struct_group() is used directly.
