With Androidx86 8.1, wificond returns "failed to get
nl80211_sta_info_tx_failed" and wificondControl returns "Invalid signal
poll result from wificond". The fix is to OR sinfo->filled with
BIT_ULL(NL80211_STA_INFO_TX_FAILED).
This missing bit is apparently not needed with NetworkManager, but it
does no harm in that case.

In commit b37f9e1c38 ("staging: rtl8723bs: Fix lines too long in
update_recvframe_attrib()."), the refactoring involved replacing
two memcmp() calls with ether_addr_equal() calls. What the author
missed is that memcmp() returns false when the two strings are equal,
whereas ether_addr_equal() returns true when the two addresses are
equal. One side effect of this error is that the strength of an
unassociated AP was much stronger than the same AP after association.
This bug is reported at bko#201611.

We return 0 unconditionally in 'rtw_wx_read32()'.
However, 'ret' is set to some error codes in several error handling paths.
Return 'ret' instead to propagate the error code.

Currently szLine[i] is being accessed before the index i is being
ranged checked. Fix this by checking the range first. Also, evaluate
the length of the string szLine just once rather than multiple times and
move the loop variable i to an inner scope and make it an int.

Pull staging and IIO updates from Greg KH:
"Here are the big staging/iio patches for 4.19-rc1.
Lots of churn here, with tons of cleanups happening in staging
drivers, a removal of an old crypto driver that no one was using
(skein), and the addition of some new IIO drivers. Also added was a
"gasket" driver from Google that needs loads of work and the erofs
filesystem.
Even with adding all of the new drivers and a new filesystem, we are
only adding about 1000 lines overall to the kernel linecount, which
shows just how much cleanup happened, and how big the unused crypto
driver was.
All of these have been in the linux-next tree for a while now with no
reported issues"

drivers/staging/rtl8188eu/include/odm.h uses an incorrect encoding
for the '...' character in two comments, which makes it one of the
few non-UTF-8 source files.
This removes the odd characters and uses the same ASCII representation
that we have in the regular rtlwifi driver. The second instance
of drivers/staging/rtl8723bs/hal/odm.h is garbled in a different way,
so I change it to be the same as well even though it is already
plain ASCII.
