Comment 2 OldManSeph 2024-12-09 00:23:36 UTC
This is a result from GCC 15 enabling "-Werror=unterminated-string-initialization" by default.

Comment 3 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2024-12-09 00:24:56 UTC
Please report this upstream on the kernel ML.

As a workaround, you can disable CONFIG_WERROR and the other DRM-specific WERROR option.

Can you attach your .config to make my life easier ?
