The lower-level driver may want to provide its own buffers. If so,
there's no need to allocate new ones. This already happens to work
just fine (since we check for size of 0 and use devm allocation), but
it's good to document it.

If platform_device_alloc() or platform_device_add_data() fail during
pcf50633_probe(), the current code ignores the return error code and
continues to attempt to allocate new platform devices for each of the
supported regulators. Instead, if any failures occur we should fail
out gracefully by cleaning up after ourselves and return the error.

Currently the Arizona core uses a devm_regulator_get against its own
device node to obtain DCVDD. The Arizona core is an MFD device and DCVDD
is usually supplied by a child node (arizona-ldo1) of the core. As
devres destruction for the MFD device will run after all its children
have been destroyed, the regulator will be destroyed before devres
calls regulator_put. This causes a warning from both the destruction of
the child node, as the regulator is still open, and from the put of the
regulator as the regulator device has already been destroyed.
This patch handles the regulator get and put without devres to avoid
this issue.

cros_ec_spi makes the assumption that a 0-length message will put the
spi chip select back to normal (non cs_toggle mode). This used to be
the case back on kernel-3.8 on the spi-s3c64xx driver but doesn't
appear to be true anymore. It seems like it was a pretty questionable
assumption to begin with, so let's fix the code to be more robust. We
know that a message with a single 0-length segment _will_ put things
back in order. Change cros_ec_spi to handle this.
This wasn't a problem on the main user of cros_ec_spi upstream (tegra)
because it specified 'google,cros-ec-spi-msg-delay'.

Merge OMAP fixes from Tony Lindgren:
Fixes for omaps for issues discovered during the merge window and
enabling of a few features that had to wait for the driver
dependencies to clear.
The fixes included are:
- Fix am43xx hard reset flags
- Fix SoC detection for DRA722
- Fix CPU OPP table for omap5
- Fix legacy mux parser bug if requested muxname is a prefix of
multiple mux entries
- Fix qspi interrupt binding that relies on the irq crossbar

- Add missing phy_sel for am43x-epos-evm
- Drop unused gic_init_irq() that is no longer needed
And the enabling of features that had driver dependencies are:
- Change dra7 to use Audio Tracking Logic clock instead of a fixed
clock now that the clock driver for it has been merged
- Enable off idle configuration for selected omaps as all the kernel
dependencies for device tree based booting are finally merged as
this is needed to get the automated PM tests working finally with
device tree based booting
- Add hwmod entry for ocp2scp3 for omap5 to get sata working as
