New build warnings

[Russell King - ARM Linux <linux@arm.linux.org.uk>]

Okay, so last night's build run shows some new warnings...

drivers/regulator/twl-regulator.c: In function 'twlreg_probe':
drivers/regulator/twl-regulator.c:1151: warning: assignment discards qualifiers from pointer target type
drivers/regulator/twl-regulator.c:1160: warning: assignment discards qualifiers from pointer target type

These two look like missing const - looks like they were introduced by:

commit 98d7bbb9929bcc14e11ac8a55245a4f2dc174e17
Author: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
Date:   Thu Jun 7 12:20:14 2012 +0200

    of: add const to struct *of_device_id.data

    Drivers should never need to modify the data of a device id. So it can
    be const which in turn allows more consts in the driver.

drivers/regulator/twl-regulator.c: At top level:
drivers/regulator/twl-regulator.c:1051: warning: 'TWLRES_INFO_CLK32KG' defined but not used

This one looks like it was caused by:

    regulator: twl: Remove references to 32kHz clock from DT bindings

    Due to the lack of a generic clock API we'd had the 32kHz clock in the
    regulator driver but this is definitely a Linux-specific thing and now
    we have a clock API hopefully the code can be moved elsewhere. Try to
    avoid getting DTs deployed relying on the 32kHz clock by removing it
    from the bindings, grep seems to tell me it's not currently used anyway.

which removes:

-#define TWLRES_OF_MATCH(comp, label) TWL_OF_MATCH(comp, TWLRES, label)
-       TWLRES_OF_MATCH("ti,twl6030-clk32kg", CLK32KG),

but completely forgets that this:

TWL6030_FIXED_RESOURCE(CLK32KG, 0x8C, 0);

defines a structure that it was using.  (Welcome to why macros are horrid
when they hide the names of stuff they create.)
