Pull char/misc driver updates from Greg KH:
"Here is the bit set of char/misc drivers for 4.19-rc1
There is a lot here, much more than normal, seems like everyone is
writing new driver subsystems these days... Anyway, major things here
are:
- new FSI driver subsystem, yet-another-powerpc low-level hardware
bus
- gnss, finally an in-kernel GPS subsystem to try to tame all of the
crazy out-of-tree drivers that have been floating around for years,
combined with some really hacky userspace implementations. This is
only for GNSS receivers, but you have to start somewhere, and this
is great to see.
Other than that, there are new slimbus drivers, new coresight drivers,
new fpga drivers, and loads of DT bindings for all of these and
existing drivers.
All of these have been in linux-next for a while with no reported
issues"

At over 4000 #includes, <linux/platform_device.h> is the 9th most
#included header file in the Linux kernel. It does not need
<linux/mod_devicetable.h>, so drop that header and explicitly add
<linux/mod_devicetable.h> to source files that need it.
4146 #include <linux/platform_device.h>
After this patch, there are 225 files that use <linux/mod_devicetable.h>,
for a reduction of around 3900 times that <linux/mod_devicetable.h>
does not have to be read & parsed.
225 #include <linux/mod_devicetable.h>
This patch was build-tested on 20 different arch-es.
It also makes these drivers SubmitChecklist#1 compliant.

We need to consistently enforce that keyed hashes cannot be used without
setting the key. To do this we need a reliable way to determine whether
a given hash algorithm is keyed or not. AF_ALG currently does this by
checking for the presence of a ->setkey() method. However, this is
actually slightly broken because the CRC-32 algorithms implement
->setkey() but can also be used without a key. (The CRC-32 "key" is not
actually a cryptographic key but rather represents the initial state.
If not overridden, then a default initial state is used.)
Prepare to fix this by introducing a flag CRYPTO_ALG_OPTIONAL_KEY which
indicates that the algorithm has a ->setkey() method, but it is not
required to be called. Then set it on all the CRC-32 algorithms.
The same also applies to the Adler-32 implementation in Lustre.
Also, the cryptd and mcryptd templates have to pass through the flag
from their underlying algorithm.

This module registers a CRC32 ("Ethernet") and a CRC32C (Castagnoli)
algorithm that make use of the STMicroelectronics STM32 crypto hardware.
Theses algorithms are compatible with the little-endian generic ones.
Both algorithms use ~0 as default seed (key).
With CRC32C the output is xored with ~0.
Using TCRYPT CRC32C speed test, this shows up to 900% speedup compared
to the crc32c-generic algorithm.
