From bedcc45c2e5d72b1c4b087b725c391441a93eee6 Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Wed, 11 Mar 2009 21:59:03 +0900 Subject: tmio_mmc: Fix use after free in remove() Update the tmio_mmc code to call mmc_free_host() when done using the private data. Without this fix the driver frees memory and then keeps on using it as private data.
