608230e733 staging: r8188eu: remove the sreset_priv structure 
last_tx_time from struct sreset_priv is no longer used now that
last_tx_complete_time is gone.

This patch removes last_tx_time. This was the last remaining component of
struct sreset_priv, we can now remove the structure itself.

After removing include/rtw_sreset.h, it turned out that some definitions
in .c files were pulled in via rtw_sreset.h. Add the required include
files directly to make compilation succeed without rtw_sreset.h.

wifi_error_status in struct sreset_priv is set in a couple of places,
its value is never used.

Remove wifi_error_status itself, the defines for the possible values and
the sreset_set_wifi_error_status function.

Rewrite the if statement in usb_write_port_complete. For purb->status ==
-EPIPE or -EPROTO, nothing should be done.

7e4c7947b4 staging: r8188eu: Use a Mutex instead of a binary Semaphore 
Use a Mutex instead of a binary Semaphore for the purpose of enforcing
mutual exclusive access to the "pwrctrl_priv" structure.

Mutexes are sleeping locks similar to Semaphores with a 'count' of one
(like binary Semaphores), however they have a simpler interface, more
efficient performance, and additional constraints.

There is no change in the logic of the new code; however it is more
simple because it gets rid of four unnecessary wrappers:
_init_pwrlock(), _enter_pwrlock(),_exit_pwrlock(), _rtw_down_sema().

Actually, there is a change in the state in which the code waits for
acquiring locks, because it makes it in an uninterruptible state
(instead the old code used down_interruptibe()). Interruptible
waits are neither required nor wanted in this driver.

Tested with ASUSTek Computer, Inc. Realtek 8188EUS [USB-N10 Nano].

race condition between r871xu_dev_remove() ->ndo_open() callback.

It's easy to see from crash log, that driver accesses released firmware
in ->ndo_open() callback. It may happen, since driver was releasing
firmware _before_ unregistering netdev. Fix it by moving
unregister_netdev() before cleaning up resources.

e7c636f2bb staging: rtl: use eth_hw_addr_set() 
Commit 406f42fa0d ("net-next: When a bond have a massive amount
of VLANs...") introduced a rbtree for faster Ethernet address look
up. To maintain netdev->dev_addr in this tree we need to make all
the writes to it got through appropriate helpers.

d9f32a101e staging: r8188eu: Remove redundant 'if' statement 
Remove the redundant first 'if' statement of two identical ones.

In rtw_cmd_thread() there are two identical 'if' statement, one
immediately after the other. They check whether or not the device is
removed or the driver is stopped and, if true, they break a 'while'
loop.

The only noteworthy context difference is that the second statement is
within a block labelled "_next". The code has a 'goto' to the "_next"
label so that the checking is performed each time the above directive
is encountered. Instead, the first 'if' is before the "_next" label.

One of the two must be removed and that it must be the one before the
label because "bSurpriseRemoved" as well as "bDriverStopped" may be
changed asynchronously by other code of the driver and so they should be
checked at each jump to "_next".

Tested with "ASUSTek Computer, Inc. Realtek 8188EUS [USB-N10 Nano]".
