[Srinivas Kandagatla]

Here are 2 minor fixes for regmap slimbus.

Thanks,
srini

[PATCH 1/2] regmap: add missing prototype for devm_init_slimbus

[Srinivas Kandagatla]

For some reason the devm variant of slimbus init is not added
into the header eventhough this __devm_regmap_init_slimbus()
is an exported function.

This patch adds this. This also fixes below warning in regmap-slimbus.c
regmap-slimbus.c:65:15: warning: symbol '__devm_regmap_init_slimbus'
 was not declared. Should it be static?
regmap-slimbus.c:65:16: warning: no previous prototype for
 '__devm_regmap_init_slimbus' [-Wmissing-prototypes]

Fixes: 7d6f7fb053ad ("regmap: add SLIMbus support")

[PATCH 2/2] regmap: slimbus: allow register offsets up to 16 bits

[Srinivas Kandagatla]

As per SLIMBus specs Value Elements and Information Elements
address map ranges from 0x000 - 0xFFF.

So allow register addresses up to 16 bits

Applied "regmap: slimbus: allow register offsets up to 16 bits" to the regmap tree

[Mark Brown]

The patch

   regmap: slimbus: allow register offsets up to 16 bits

has been applied to the regmap tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap.git 

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
