0e820ab601 mfd: Correct use after free for t7l66xb
The structure t7l66xb should not be freed before the subsequent references
to its fields in the arguments to clk_put.  Furthermore, this structure is
allocated near the beginning of the function, and a goto to the label
err_noirq appears after a successful allocation, so it would seem that the
kfree should be moved down below this label.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@
expression x,e;
identifier f;
iterator I;
statement S;
@@

*kfree(x);
... when != &x
    when != x = e
    when != I(x,...) S
*x->f
// </smpl>

64e8867ba8 mfd: tmio_mmc hardware abstraction for CNF area
This patch abstracts out the CNF area code from tmio_mmc which
is not present in all hardware that can use this driver. This
is required so that we can support non-toshiba based hardware.

4d3792e054 mfd: fix tmio related warnings
We can not have .driver_data as const since platform_set_drvdata() doesnt take
a const.
The hclk mmc_data field can be const though.

f0e46cc497 MFD,mmc: tmio_mmc: make HCLK configurable
The Toshiba parts all have a 24 MHz HCLK, but HTC ASIC3 has a 24.576 MHz HCLK
and AMD Imageon w228x's HCLK is 80 MHz. With this patch, the MFD driver
provides the HCLK frequency to tmio_mmc via mfd_cell->driver_data.

3446d4bb93 mfd: Storage class should be before const qualifier
The C99 specification states in section 6.11.5:

The placement of a storage-class specifier other than at the beginning
of the declaration specifiers in a declaration is an obsolescent
feature.

This patch updates the remaining two TMIO drivers to use the clock API
