From ece5df874d3a80fcade92ca3b3877bd78dbb6116 Mon Sep 17 00:00:00 2001 From: Danielle Ratson Date: Mon, 17 May 2021 20:03:56 +0300 Subject: [PATCH] mlxsw: spectrum_buffers: Switch function arguments In the call path: mlxsw_sp_hdroom_bufs_reset_sizes() mlxsw_sp_hdroom_int_buf_size_get() ->int_buf_size_get() The 'speed' and 'mtu' arguments were mistakenly switched twice. The two bugs thus canceled each other. Clean this up by switching the arguments in both call sites, so that they are passed in the right order. Found during manual code inspection.
