The value of ee1004_current_page applies to all SPD eeproms connected
to the adapter. Therefore it's sufficient if we set ee1004_current_page
when the first device is added.

i2c_new_dummy_device() calls i2c_new_client_device() that complains
if it fails to create the device. Therefore we don't have to emit an
error message in case of failure. In addition ensure that
ee1004_set_page is only set if creating the device succeeded.

We have to read 512 bytes only, therefore read performance isn't really
a concern. Don't bother the user if i2c block read isn't supported.
For i2c_smbus_read_i2c_block_data_or_emulated() to work it's sufficient
if I2C_FUNC_SMBUS_READ_I2C_BLOCK or I2C_FUNC_SMBUS_READ_BYTE_DATA is
supported. Therefore remove the check for I2C_FUNC_SMBUS_READ_WORD_DATA.
In addition check for I2C_FUNC_SMBUS_WRITE_BYTE (included in
I2C_FUNC_SMBUS_BYTE) which is needed for setting the page.

i2c_smbus_read_i2c_block_data_or_emulated() checks its length argument,
so we don't have to do it. In addition remove the unlikely hint from
the checks, we do i2c reads and therefore are in a slow path.

Simplify code and turn 'pvpanic_probe()' into a managed resource version.
This simplify callers that don't need to do some clean-up on error in the
probe and on remove.
Update pvpanic-mmio.c and pvpanic-pci.c accordingly.
'pvpanic_remove()' don't need to be exported anymore.

The opening comment mark '/**' is used for highlighting the beginning of

The header for drivers/ipack/carriers/tpci200 follows this syntax, but the
content inside does not comply with kernel-doc.
This line was probably not meant for kernel-doc parsing, but is parsed
due to the presence of kernel-doc like comment syntax(i.e, '/**'), which
causes unexpected warning from kernel-doc.
For e.g., running scripts/kernel-doc -none on

The XillyUSB driver is the USB variant for the Xillybus FPGA IP core.
Even though it presents a nearly identical API on the FPGA and host,
it's almost a complete rewrite of the driver: The framework for exchanging
data on a USB bus is fundamentally different from doing the same with a
PCIe interface, which leaves very little in common between the existing
driver and the new one for XillyUSB.

This patch is a preparation for adding another related driver, XillyUSB.
In order to share some code between the existing Xillybus driver and the
one to be added, some functions are moved to xillybus_class.c
XILLYBUS_CLASS is added to Kconfig and is common to all drivers in this
group. The relation with the existing XILLYBUS symbol is "select" rather
than "depends on" XILLYBUS_CLASS, or else "make olddefconfig" will silently
turn off XILLYBUS, which is currently enabled in several distributions.
XILLYBUS_CLASS doesn't depend on anything else, hence using it with
"select" poses no risk for a broken configuration.
After the future addition of the XillyUSB module, the tree of symbols
will be as follows:
XILLYBUS_CLASS --+-- XILLYBUS --+-- XILLYBUS_PCIE
| |
| +-- XILLYBUS_OF
|
+-- XILLYUSB
XILLYBUS is for drivers based upon memory registers + DMA-based interfaces,
and it's combined with XILLYBUS_PCIE and/or XILLYBUS_OF.
XILLYUSB is for the USB variant only.
Or a more detailed, bottom-up outline:
* CONFIG_XILLYBUS_PCIE -> xillybus_pcie.c: Functions related to PCIe.
* CONFIG_XILLYBUS_OF -> xillybus_of.c: Functions related to Xillybus as a
peripheral on an FPGA / Processor combo chip.
* CONFIG_XILLYBUS -> xillybus_core.c: Functions that are common to the two
above, mainly access to the peripheral with memory-mapped registers and
DMA.
* CONFIG_XILLYUSB -> xillyusb.c: The driver for the USB variant, accesses
the peripheral through the USB framework.
* CONFIG_XILLYBUS_CLASS -> xillybus_class.c: The new module, which contains
the class and API parts that would otherwise appear both in
xillybus_core.c and xillyusb.c. Contains utility functions for the two
latter.
And since I'm at it, comments on the module names are added in the
Kconfig's help part.
The functions are exported with the non-GPL EXPORT_SYMBOL (a matter of
taste).

container_of() only returns NULL if the passed pointer is NULL _and_ if
the embedded element is the first element of the structure. Even if that
is the case, testing against it is misleading and possibly dangerous
because the position of the embedded element may change. In this case,
the check is unnecessary since it is known that file->private_data is
never NULL for an open file, and container_of() will therefore also
never be NULL. Drop the check.

Added a sysfs entry to support writing to the offset register on page1.
This register is used to calibrate the chip canceling offset errors in the
current ADC. This means that, over time, reading the IAD register will not
return the correct current measurement, it will have an offset. Writing to
the offset register if the two's complement of the current register while
passing zero current to the load will calibrate the measurements. This
change was tested on real hardware and it was able to calibrate the chip
correctly.

Here is a big set of char/misc/other driver fixes for 5.13-rc3.
The majority here is the fallout of the umn.edu re-review of all prior
submissions. That resulted in a bunch of reverts along with the
"correct" changes made, such that there is no regression of any of the
potential fixes that were made by those individuals. I would like to
thank the over 80 different developers who helped with the review and
fixes for this mess.
Other than that, there's a few habanna driver fixes for reported issues,
and some dyndbg fixes for reported problems.
All of these have been in linux-next for a while with no reported
problems.

Merge tag 'quota_for_v5.13-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs
Pull quota fixes from Jan Kara:
"The most important part in the pull is disablement of the new syscall
quotactl_path() which was added in rc1.
The reason is some people at LWN discussion pointed out dirfd would be
useful for this path based syscall and Christian Brauner agreed.
Without dirfd it may be indeed problematic for containers. So let's
just disable the syscall for now when it doesn't have users yet so
that we have more time to mull over how to best specify the filesystem
we want to work on"

Pull mount_setattr fix from Christian Brauner:
"This makes an underlying idmapping assumption more explicit.
We currently don't have any filesystems that support idmapped mounts
which are mountable inside a user namespace, i.e. where s_user_ns !=
init_user_ns. That was a deliberate decision for now as userns root
can just mount the filesystem themselves.
Express this restriction explicitly and enforce it until there's a
real use-case for this. This way we can notice it and will have a
chance to adapt and audit our translation helpers and fstests
appropriately if we need to support such filesystems"
