From 41a24a29142dd0352de965c40b840a90d6e55f6c Mon Sep 17 00:00:00 2001 From: Avinash Patil Date: Fri, 7 Feb 2014 16:27:29 -0800 Subject: mwifiex: make tos_to_tid_inv part of mwifiex_private structure tos_to_tid_inv values are needed even during TDLS restore operations. Currently tos_to_tid_inv is part of wmm.c and is declared static. Make it part of private structure so that it can be used in other files as well.
