Here's an assortment of drive-by fixes for the new AMD SPI driver.
All of them are compile-tested only.
Lukas Wunner (5):
spi: amd: Fix duplicate iounmap in error path
spi: amd: Pass probe errors back to driver core
spi: amd: Drop duplicate driver data assignments
spi: amd: Fix refcount underflow on remove
spi: amd: Drop superfluous member from struct amd_spi

The AMD SPI driver calls spi_master_put() in its ->remove() hook even
though the preceding call to spi_unregister_master() already drops a
ref, thus leading to a refcount underflow. Drop the superfluous call
to spi_master_put().
This only leaves the call to spi_unregister_master() in the ->remove()
hook, so it's safe to change the ->probe() hook to use the devm version
of spi_register_master() and drop the ->remove() hook altogether.

Sparse reports a warning at atmel_spi_next_xfer_dma_submit()
warning: context imbalance in atmel_spi_next_xfer_dma_submit()
- unexpected unlock
The root cause is the missing annotation
at atmel_spi_next_xfer_dma_submit()
Add the missing __must_hold(&as->lock) annotation

Pull driver core fixes from Greg KH:
"Here are some small firmware/driver core/debugfs fixes for 5.7-rc3.
The debugfs change is now possible as now the last users of
debugfs_create_u32() have been fixed up in the different trees that
got merged into 5.7-rc1, and I don't want it creeping back in.
The firmware changes did cause a regression in linux-next, so the
final patch here reverts part of that, re-exporting the symbol to
resolve that issue. All of these patches, with the exception of the
final one, have been in linux-next with only that one reported issue"

leading to a window at boot when the strict mapping wasn't enforced.
- A fix to enable our KUAP (kernel user access prevention) debugging on
PPC32.
- A build fix for clang in lib/mpi.

Pull more Devicetree fixes from Rob Herring:
"A couple of schema and kbuild fixes"
* tag 'devicetree-fixes-for-5.7-2' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux:
dt-bindings: phy: qcom-qusb2: Fix defaults
dt-bindings: Fix erroneous 'additionalProperties'
dt-bindings: Fix command line length limit calling dt-mk-schema
dt-bindings: Re-enable core schemas for dtbs_check
Christoph's patch removed two unsused exported symbols, however, one
symbol is used by the firmware_loader itself. If CONFIG_FW_LOADER=m so
the firmware_loader is modular but CONFIG_FW_LOADER_USER_HELPER=y we fail
the build at mostpost.
ERROR: modpost: "fw_fallback_config" [drivers/base/firmware_loader/firmware_class.ko] undefined!
This happens because the variable fw_fallback_config is built into the
kernel if CONFIG_FW_LOADER_USER_HELPER=y always, so we need to grant
access to the firmware loader module by exporting it.
Revert only one hunk from his patch.
