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driver and replaced it with a newer version of the driver that had been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 89939e8906 ("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 ae7471cae0 ("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 ]

Add entry for CFG80211 to reflect that it is currently being worked on
and is a desirable feature to have for this driver. Leave entries for
LIB80211 and MAC80211 in case anyone else wishes to work on them - they
can always be removed later, but MAC80211 in particular would certainly
be good to aim for. Also, include an entry for improving error handling,
as this is another goal of the cleanup effort.

There are only two definitions from ethernet.h used in the driver.
Namely:
#define ETHERNET_HEADER_SIZE 14 /* Ethernet Header Length */
#define LLC_HEADER_SIZE 6 /* LLC Header Length */
Both are only used in the file core/rtw_recv.c. Replace the usage of
ETHERNET_HEADER_SIZE with ETH_HLEN, move the definition of LLC_HEADER_SIZE
into rtw_recv.h and remove the now unused ethernet.h header file.

Remove the function _rtw_zvmalloc from os_dep/osdep_service.c, as this
function is now unused and is just an inline wrapper around vmalloc
which zeroes out the memory. All previous callers have been converted to
use vzalloc. Also remove the declaration from include/osdep_service.h.
It is considered generally bad practice to declare functions as inline in
the majority of cases, as not only can this qualifier be ignored by the
compiler but the compiler generally makes good decisions about inlining
anyway.

Convert all rtw_zvmalloc calls within the driver to use the existing
kernel vzalloc function, which has the same semantics. Also rewrite the
two places where it is mentioned in comments to say vzalloc, and remove
the redundant cast to struct adapter * in ./os_dep/usb_intf.c as vzalloc
returns void *.
The reason for the conversion is that rtw_zvmalloc is just a
preprocessor definition for _rtw_zvmalloc which itself is just an inline
wrapper around vmalloc which then zeroes the memory out. As vzalloc does
the same thing via usage of __GFP_ZERO, this code is redundant and can
subsequently be removed.
