3.6-stable review patch. If anyone has any objections, please let me know.
------------------ From: Guennadi Liakhovetski <[email protected]> commit a0d28ba01ebd048b4ba418142b37f5cf80e6d156 upstream. A recent commit "mmc: sh_mmcif: fix clock management" has introduced a use after free bug in sh_mmcif.c: in sh_mmcif_remove() the call to mmc_free_host() frees private driver data, therefore using it afterwards is a bug. Revert that hunk.
