2.6.34-stable review patch.  If anyone has any objections, please let me know.


From: Linus Walleij <linus.walleij@stericsson.com>

commit ea208f646c8fb91c39c852e952fc911e1ad045ab upstream.

This fixes a bug in mm/init.c when freeing the TCM compile memory,
this was being referred to as a char * which is incorrect: this
will dereference the pointer and feed in the value at the location
instead of the address to it. Change it to a plain char and use
&(char) to reference it.
