The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
The driver adapted here suffers from this wrong assumption. Returning
-EBUSY if there are still users results in resource leaks and probably a
crash. Also further down passing the error code of caam_jr_shutdown() to
the caller only results in another error message and has no further
consequences compared to returning zero.
Still convert the driver to return no value in the remove callback. This
also allows to drop caam_jr_platform_shutdown() as the only function
called by it now has the same prototype.

The stm32 crc32 algorithms set a nonzero alignmask, but they don't seem
to actually need it. Their ->update function already has code that
handles aligning the data to the same alignment that the alignmask
specifies, their ->setkey function already uses get_unaligned_le32(),
and their ->final function already uses put_unaligned_le32().
Therefore, stop setting the alignmask. This will allow these algorithms
to keep being registered after alignmask support is removed from shash.

For the t7 and older SoC families, the CMD_CFG_ERROR has no effect.
Starting from SoC family C3, setting this bit without SG LINK data
address will cause the controller to generate an IRQ and stop working.
To fix it, don't set the bit CMD_CFG_ERROR anymore.

Currently, netlink notifications are sent for individual remote entries
and not for the entire MDB entry itself.
Subsequent patches are going to add MDB get support which will require
the VXLAN driver to reply with an entire MDB entry.
Therefore, as a preparation, factor out a helper to calculate the size
of an individual remote entry. When determining the size of the reply
this helper will be invoked for each remote entry in the MDB entry.
No functional changes intended.

The Nuvoton NPCM Video Capture/Differentiation Engine (VCD) and Encoding
Compression Engine (ECE) are only present on Nuvoton NPCM SoCs. Hence
add a dependency on ARCH_NPCM, to prevent asking the user about these
drivers when configuring a kernel without Nuvoton NPCM Architecture
support.

Multi-socket systems have a separate PLIC in each socket, so __plic_init()
is invoked for each PLIC. __plic_init() registers syscore operations, which
obviously fails on the second invocation.
Move it into the already existing condition for installing the CPU hotplug
state so it is only invoked once when the first PLIC is initialized.

More than 1/3 of the n_gsm code has been contributed by us in the last
1.5 years, completing conformance with the standard and stabilizing the
driver:
- added UI (unnumbered information) frame support
- added PN (parameter negotiation) message handling and function support
- added optional keep-alive control link supervision via test messages
- added TIOCM_OUT1 and TIOCM_OUT2 to allow responder to operate as modem
- added TIOCMIWAIT support on virtual ttys
- added additional ioctls and parameters to configure the new functions
- added overall locking mechanism to avoid data race conditions
- added outgoing data flow to decouple physical from virtual tty handling
for better performance and to avoid dead-locks
- fixed advanced option mode implementation
- fixed convergence layer type 2 implementation
- fixed handling of CLD (multiplexer close down) messages
- fixed broken muxer close down procedure
- and many more bug fixes
With this most of our initial RFC has been implemented. It gives the driver
a quality boost unseen in the decade before.
Add a copyright notice to the n_gsm files to highlight this contribution.

Use preferred device_get_match_data() instead of of_match_device() to
get the driver match data in a single step without the unnecessary
intermediate match pointer.
With this, adjust the includes to explicitly include the correct
headers. That also serves as preparation to remove implicit includes within
the DT headers. of_platform.h currently includes platform_device.h among
others.

The iommu_create_device_direct_mappings() only needs to flush the caches
when the mappings are changed in the affected domain. This is not true
for non-DMA domains, or for devices attached to the domain that have no
reserved regions. To avoid unnecessary cache invalidations, add a check
before iommu_flush_iotlb_all().

Now that the driver core allows for struct class to be in read-only

placing them into read-only memory, instead of having to be dynamically
allocated at runtime.
