From: Jiri Pirko Date: Fri, 8 Apr 2016 17:11:21 +0000 (+0200) Subject: mlxsw: Move devlink port registration into common core code X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=932762b69a282d3fa12febc1a02628f0fb79a1b8;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git mlxsw: Move devlink port registration into common core code Remove devlink port reg/unreg from spectrum and switchx2 code and rather do the common work in core. That also ensures code separation where devlink is only used in core.c. Signed-off-by: Jiri Pirko Reviewed-by: Ido Schimmel Signed-off-by: David S.
