[PATCH 2/7] mfd: ab8500-debugfs: Prevent initialised field from being over-written

[Lee Jones]

Due to the lack of parity in the way array fields have been named/
numbered, a mistake was made where more debug fields were declared
than actually existed.  In doing so, 2 fields were added, which
although unclear, were already declared in the array.  The result
was that the latter declarations trashed the former ones.

This patch places the array back in the correct order and removes
the offending NULL entries.

While we're at it, let's ensure this doesn't happen again by naming
each field properly and add a new *_LAST define to describe how
many fields there should be.

Looks good, I seem to have done the same thing. Also didn't submit,
so keep your version.

I tend to include the exact warning in the changelog, which here was

drivers/mfd/omap-usb-host.c:165:18: warning: type qualifiers ignored on function return type [-Wignored-qualifiers]

Subject: [PATCH] mfd: tps65912: move regmap config into core driver

When building with extra warnings enabled, most files including
linux/mfd/tps65912.h warn about a static variable defined in the
header:

include/linux/mfd/tps65912.h:331:35: warning: 'tps65912_regmap_config' defined but not used [-Wunused-const-variable=]

We also duplicate the data structure between the i2c and spi front-end
drivers. Moving it into the driver code avoids the warning and
the duplication.

This function was actually used in the vendor tree to deal with DVFS,
implemented a system wide PM QoS thing.
I guess those hacks never made it upstream. :-)
