Here's the "big" staging/iio pull request for 4.10-rc1.
Not as big as 4.9 was, but still just over a thousand changes. We
almost broke even of lines added vs. removed, as the slicoss driver was
removed (got a "clean" driver for the same hardware through the netdev
tree), and some iio drivers were also dropped, but I think we ended up
adding a few thousand lines to the source tree in the end. Other than
that it's a lot of minor fixes all over the place, nothing major stands
out at all.
All of these have been in linux-next for a while. There will be a merge
conflict with Al's vfs tree in the lustre code, but the resolution for
that should be pretty simple, that too has been in linux-next.

The rtllib_rx_extract_addr() is supposed to set up the mac addresses
for four possible cases, based on two bits of input data. For
some reason, gcc decides that it's possible that none of the these
four cases apply and the addresses remain uninitialized:
drivers/staging/rtl8192e/rtllib_rx.c: In function ‘rtllib_rx_InfraAdhoc’:
include/linux/etherdevice.h:316:61: error: ‘*((void *)&dst+4)’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
drivers/staging/rtl8192e/rtllib_rx.c:1318:5: note: ‘*((void *)&dst+4)’ was declared here
ded from /git/arm-soc/drivers/staging/rtl8192e/rtllib_rx.c:40:0:
include/linux/etherdevice.h:316:36: error: ‘dst’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
drivers/staging/rtl8192e/rtllib_rx.c:1318:5: note: ‘dst’ was declared here
This warning is clearly nonsense, but changing the last case into
'default' makes it obvious to the compiler too, which avoids the
warning and probably leads to better object code too.
As the same warning appears in other files that have the exact
same code, I'm fixing it in both rtl8192e and rtl8192u, even
though I did not observe it for the latter.

With centralized MTU checking, there's nothing productive done by
eth_change_mtu that isn't already done in dev_set_mtu, so mark it as
deprecated and remove all usage of it in the kernel. All callers have been
audited for calls to alloc_etherdev* or ether_setup directly, which means
they all have a valid dev->min_mtu and dev->max_mtu. Now eth_change_mtu
prints out a netdev_warn about being deprecated, for the benefit of
out-of-tree drivers that might be utilizing it.
Of note, dvb_net.c actually had dev->mtu = 4096, while using
eth_change_mtu, meaning that if you ever tried changing it's mtu, you
couldn't set it above 1500 anymore. It's now getting dev->max_mtu also set
to 4096 to remedy that.

woken up from their sleep and have been doing a great job in cleaning up

a trans_start struct member exists twice:
- in struct net_device (legacy)
- in struct netdev_queue
Instead of open-coding dev->trans_start usage to obtain the current
trans_start value, use dev_trans_start() instead.
This is not exactly the same, as dev_trans_start also considers
the trans_start values of the netdev queues owned by the device
and provides the most recent one.
For legacy devices this doesn't matter as dev_trans_start can cope
with netdev trans_start values of 0 (they are ignored).
This is a prerequisite to eventual removal of dev->trans_start.
