This function is supposed to return zero on success or negative error
codes on error.  Unfortunately, there is a bug so it sometimes returns
non-zero, positive numbers on success.

I noticed this bug during review and I can't test it.  It does appear
that the return is sometimes propogated back to _regmap_read() where all
non-zero returns are treated as failure so this may affect run time.

attribute_groups are not supposed to change at runtime. All functions
working with attribute_groups provided by &lt;linux/sysfs.h&gt; work with const
attribute_group. So mark the non-const structs as const.

File size before:
   text	   data	    bss	    dec	    hex	filename
  16298	   1009	    184	  17491	   4453	drivers/mfd/ab8500-core.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
  16490	    817	    184	  17491	   4453	drivers/mfd/ab8500-core.o

We didn't have proper device tree bindings for this clock,
I standardized it to use the exact chipname so let's rename
it "ab8500-clk" and rectify the device tree compatible string
to "stericsson,ab8500-clk".

<title>mfd: ab8500-core: Make it explicitly non-modular</title>

The Kconfig currently controlling compilation of this code is:

drivers/mfd/Kconfig:config AB8500_CORE
drivers/mfd/Kconfig:    bool "ST-Ericsson AB8500 Mixed Signal Power Management chip"

...meaning that it currently is not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and it allows us to drop the ".remove"
code for non-modular drivers.

Since module_init was not in use by this code, the init ordering
remains unchanged with this commit.

We replace module.h with moduleparam.h ; the latter since this file
was implicitly relying on getting it.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

Except for the constant DB8500_PRCMU_FW_VERSION_OFFSET number, nothing
is ever passed through the platform data and used in a driver, so we
can simply stop passing it around.

<title>mfd: Kill off set_irq_flags usage</title>

set_irq_flags is ARM specific with custom flags which have genirq
equivalents. Convert drivers to use the genirq interfaces directly, so we
can kill off set_irq_flags. The translation of flags is as follows:

IRQF_VALID -&gt; !IRQ_NOREQUEST
IRQF_PROBE -&gt; !IRQ_NOPROBE
IRQF_NOAUTOEN -&gt; IRQ_NOAUTOEN

For IRQs managed by an irqdomain, the irqdomain core code handles clearing
and setting IRQ_NOREQUEST already, so there is no need to do this in
.map() functions and we can simply remove the set_irq_flags calls. Some
users also modify IRQ_NOPROBE and this has been maintained although it
is not clear that is really needed. There appears to be a great deal of
blind copy and paste of this code.
