From 3d48203847c096afaddb2ba3c0623cfe49e91fa3 Mon Sep 17 00:00:00 2001 From: Avinash Patil Date: Fri, 15 Feb 2013 21:37:54 -0800 Subject: [PATCH] mwifiex: fix empty TX ring check for PCIe8897 while unloading driver While unloading driver, we free all pending TX packets by flushing TX ring. There is unhandled case for PCIE8897 while checking for ring empty condition. This patch adds the handling by calling mwifiex_pcie_txbd_empty().
