From: Gabriele Monaco Date: Fri, 27 Dec 2024 14:47:46 +0000 (+0100) Subject: verification/dot2k: Unify main.c templates X-Git-Tag: v6.14-rc1~83^2~20 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=ca08e071c59d96cb1db19b20ba70e9db7b9d5791;p=thirdparty%2Fkernel%2Flinux.git verification/dot2k: Unify main.c templates dot2k has 3 templates, one per monitor type, but the only difference among them is the `DECLARE_DA_MON_*` call, keeping 3 almost identical templates requires more work whenever we introduce a change. This patch removes the 3 dot2k templates and replaces them with a generic one, we then adjust the model type from the script.
