staging: wilc1000: Fix bssid buffer offset in Txq
Commit
46949b48568b ("staging: wilc1000: New cfg packet
format in handle_set_wfi_drv_handler") updated the frame
format sent from host to the firmware. The code to update
the bssid offset in the new frame was part of a second
patch in the series which did not make it in and thus
causes connection problems after associating to an AP.
This fix adds the proper offset of the bssid value in the
Tx queue buffer to fix the connection issues.

When the row scan order is reversed (the default) we also need to
reverse the column scan order. This was not done previously, resulting

Also add support for 180 degree display rotation, in which case simply
disable reversed row and column scan order.

Loopback has its own internal method for tracking and timing out
asynchronous operations however previous patches make it possible to use
functionality provided by operation.c to do this instead. Using the code in
operation.c means we can completely subtract the timer, the work-queue, the
kref and the cringe-worthy 'pending' flag. The completion callback
triggered by operation.c will provide an authoritative result code -
including -ETIMEDOUT for asynchronous operations.

unexpected page allocation failures.
My testing indicates that the trouble started between v4.5 and v4.6

Using the dirty_tx before acquiring the spin lock is clearly

ipv6: flowlabel: do not leave opt->tot_len with garbage
When syzkaller team brought us a C repro for the crash [1] that
had been reported many times in the past, I finally could find
the root cause.
If FlowLabel info is merged by fl6_merge_options(), we leave
part of the opt_space storage provided by udp/raw/l2tp with random value
in opt_space.tot_len, unless a control message was provided at sendmsg()
time.
Then ip6_setup_cork() would use this random value to perform a kzalloc()
call. Undefined behavior and crashes.
Fix is to properly set tot_len in fl6_merge_options()
At the same time, we can also avoid consuming memory and cpu cycles
to clear it, if every option is copied via a kmemdup(). This is the
change in ip6_setup_cork().

of_mdio: Fix broken PHY IRQ in case of probe deferral
If an Ethernet PHY is initialized before the interrupt controller it is
connected to, a message like the following is printed:
irq: no irq domain found for /interrupt-controller@
e61c0000 !
However, the actual error is ignored, leading to a non-functional (POLL)
PHY interrupt later:
Micrel KSZ8041RNLI
ee700000.ethernet-
ffffffff:01: attached PHY driver [Micrel KSZ8041RNLI] (mii_bus:phy_addr=
ee700000.ethernet-
ffffffff:01, irq=POLL)
Depending on whether the PHY driver will fall back to polling, Ethernet
may or may not work.
To fix this:
1. Switch of_mdiobus_register_phy() from irq_of_parse_and_map() to
of_irq_get().
Unlike the former, the latter returns -EPROBE_DEFER if the
interrupt controller is not yet available, so this condition can be
detected.
Other errors are handled the same as before, i.e. use the passed
mdio->irq[addr] as interrupt.
2. Propagate and handle errors from of_mdiobus_register_phy() and
of_mdiobus_register_device().

Currently mlxsw only offloads tunnels that are configured with TTL of "inherit"

On this error, skb_zerocopy_stream_iter resets the skb to its state

datagram callers, as the skb may have data from a previous send call.
__pskb_trim calls skb_condense for unowned skbs, which adjusts their
truesize. These tcp skbuffs are owned and their truesize must add up
to sk_wmem_queued. But they match because their skb->sk is NULL until
tcp_transmit_skb.
Temporarily set skb->sk when calling __pskb_trim to signal that the

upper right range border when marking in find_good_pkt_pointers()
with BPF_JLT and BPF_JLE. It's not really harmful given access
up to pkt_end is always safe, but we should nevertheless correct
the range marking before it becomes ABI. If pkt_data' denotes a
pkt_data derived pointer (pkt_data + X), then for pkt_data' < pkt_end
in the true branch as well as for pkt_end <= pkt_data' in the false
branch we mark the range with X although it should really be X - 1
in these cases. For example, X could be pkt_end - pkt_data, then
when testing for pkt_data' < pkt_end the verifier simulation cannot
deduce that a byte load of pkt_data' - 1 would succeed in this

The DACrrcS085 (rr = 08/10/12, c = 2/4) family of SPI DACs was
inherited by TI when they acquired National Semiconductor in 2011.
This driver was developed for and tested with the DAC082S085 built into
the Revolution Pi by KUNBUS, but should work with any of the other
chips as they share the same programming interface.
There is also a family of I2C DACs with just a single channel called
DACrr1C08x (rr = 08/10/12, x = 1/5). Their programming interface is
very similar and it should be possible to extend the driver for these
chips with moderate effort. Alternatively they could be integrated into
ad5446.c. (The AD5301/AD5311/AD5321 use different power-down modes but
otherwise appear to be comparable.)
Furthermore there is a family of 8-channel DACs called DACrr8S085
(rr = 08/10/12) as well as two 16-bit DACs called DAC161Sxxx
(xxx = 055/997). These are more complicated devices with support for
daisy-chaining and the ability to power down each channel separately.

staging: iio: tsl2x7x: correct alignment of parenthesis
Correct error from checkpatch.pl to improve code readibility: Alignment
should match open parenthesis. An unnecessary cast to 'struct
tsl2x7x_lux *' was removed and the return value of static definition of
in_illuminance0_calibscale_available_show() was put on its own line
due to the length of that sysfs attribute.

staging: iio: tsl2x7x: correct alignment of parenthesis
Correct error from checkpatch.pl to improve code readibility: Alignment
should match open parenthesis. This involved shortening the name of
tsl2x7x_als_gainadj and tsl2x7x_prx_gainadj to tsl2x7x_als_gain and
tsl2x7x_prx_gain respectively. This also required removing the
ch0lux and ch1lux local variables in order to get the line short
enough.

staging: iio: tsl2x7x: changed #defines to be aligned on the same column
Some of the existing #defines have tabs between the name, and the value,
while others have spaces. The alignment of the values mostly has a
consistent layout, but there are some that don't. Change all of the
defines so that the name and value is separated by tabs and all of the
values start on the same column to increase code readability. This patch
also removes the unnecessary parentheses around the value of
TSL2X7X_MAX_TIMER_CNT.
