Pull IIO and staging driver updates from Greg KH:
"Here is the big set of staging and IIO driver updates for 5.15-rc1.
Also included in here are the counter driver subsystem updates as the
IIO drivers needed them.
Lots of churn in some staging drivers, we dropped the "old" rtl8188eu
driver and replaced it with a newer version of the driver that had
been maintained out-of-tree by Larry with the end goal of actually
being able to get this driver out of staging eventually. Despite that
driver being "newer" the line count of this pull request is going up.
Some drivers moved out of staging as well, which is always nice to
see, that is why there are additions to the mfc and misc driver
subsystems. All of these were acked by the various subsystem
maintainers involved.
But by far, as normal, it's coding style cleanups all over the
drivers/staging/ tree in here.
Full details of these changes are in the shortlog.
All of these have been in linux-next for a while with no reported
problems"
[ Note: the r8188eu merge clashed with commit 89939e890605 ("staging:
rtlwifi: use siocdevprivate") from the networking tree. When resolving
the issue, I noted that the whole r8188eu rtw_android code is dead
since commit ae7471cae00a ("staging: r8188eu: remove rtw_ioctl
function").
End result: the merge resolution was to throw all of that away,
rather than do the mindless fixup to code that isn't actually
reachable - Linus ]

In order to support more coalesce parameters through netlink,
add two new parameter kernel_coal and extack for .set_coalesce
and .get_coalesce, then some extra info can return to user with

All kernel devlink implementations call to devlink_alloc() during
initialization routine for specific device which is used later as
a parent device for devlink_register().
Such late device assignment causes to the situation which requires us to
call to device_register() before setting other parameters, but that call
opens devlink to the world and makes accessible for the netlink users.
Any attempt to move devlink_register() to be the last call generates the
following error due to access to the devlink->dev pointer.
[ 8.758862] devlink_nl_param_fill+0x2e8/0xe50
[ 8.760305] devlink_param_notify+0x6d/0x180
[ 8.760435] __devlink_params_register+0x2f1/0x670
[ 8.760558] devlink_params_register+0x1e/0x20
The simple change of API to set devlink device in the devlink_alloc()
instead of devlink_register() fixes all this above and ensures that
prior to call to devlink_register() everything already set.

This patch changes msleep() to usleep_range() based on

for small msec(1ms - 20ms) because msleep() will often sleep longer than
the desired value. Issue found by checkpatch.

strlcpy is marked as deprecated in Documentation/process/deprecated.rst,
and there is no functional difference when the caller expects truncation
(when not checking the return value). strscpy is relatively better as it
also avoids scanning the whole source string.

The debugging code in the following ifdef land
- QL_ALL_DUMP
- QL_REG_DUMP
- QL_DEV_DUMP
- QL_CB_DUMP
- QL_IB_DUMP
- QL_OB_DUMP
becomes unnecessary because,
- Device status and general registers can be obtained by ethtool.
- Coredump can be done via devlink health reporter.
- Structure related to the hardware (struct ql_adapter) can be obtained
by crash or drgn.

Initialize devlink health dump framework for the qlge driver so the
coredump could be done via devlink.
struct qlge_adapter is now used as the private data structure of
struct devlink so it could exist independently of struct net_device
and devlink reload could be supported in the future. The private data
of PCIe driver now points to qlge_adapter.
Since devlink_alloc will zero out struct qlge_adapter, memset in
qlge_init_device is not necessary.

qlogic drivers
To avoid namespace clashes with other qlogic drivers and also for the
sake of naming consistency, use the "qlge_" prefix as suggested in
drivers/staging/qlge/TODO,
- For existing ql_ prefix,
sed -i "s/ql_/qlge_/g" *.{c,h}
- for structs not having a prefix
1. get a list of structs
grep "struct.*{" qlge.
2. add qlge_ for each struct, e.g.,
sed -i "s/ib_ae_iocb_rsp/qlge_ib_ae_iocb_rsp/g" *.{c,h}

The legacy API wrappers in include/linux/pci-dma-compat.h
should go away as it creates unnecessary midlayering
for include/linux/dma-mapping.h APIs, instead use dma-mapping.h
APIs directly.

The method struct pci_error_handlers.error_detected() is defined and
documented as taking an 'enum pci_channel_state' for the second argument,
but most drivers use 'pci_channel_state_t' instead.
This 'pci_channel_state_t' is not a typedef for the enum but a typedef for
a bitwise type in order to have better/stricter typechecking.
Consolidate everything by using 'pci_channel_state_t' in the method's
definition, in the related helpers and in the drivers.
Enforce use of 'pci_channel_state_t' by replacing 'enum pci_channel_state'
with an anonymous 'enum'.
Note: Currently, from a typechecking point of view this patch changes
nothing because only the constants defined by the enum are bitwise, not the
enum itself (sparse doesn't have the notion of 'bitwise enum'). This may
change in some not too far future, hence the patch.

Drivers should not use legacy power management as they have to manage power
states and related operations, for the device, themselves. This driver was
handling them with the help of PCI helper functions like
pci_save/restore_state(), pci_enable/disable_device(), etc.
With generic PM, all essentials will be handled by the PCI core. Driver
needs to do only device-specific operations.
The driver was also using pci_enable_wake(...,..., 0) to disable wake. Use
device_wakeup_disable() instead.
Compile-tested only.
