From: Moshe Shemesh Date: Fri, 18 Feb 2022 07:36:20 +0000 (+0200) Subject: net/mlx5: Move debugfs entries to separate struct X-Git-Tag: v6.1-rc5~1746^2~129^2~9 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=66771a1c729e816dc84e29ba555013b6e722fb22;p=platform%2Fkernel%2Flinux-starfive.git net/mlx5: Move debugfs entries to separate struct Move the debugfs entry pointers under priv to their own struct. Add get function for device debugfs root.
