In commit 022d00ee0b ("ASoC: lpass-platform: Fix broken pcm data
usage") the stream specific information initialization was broken, with
the dma channel information not being initialized if there was no
alloc_dma_channel() helper function.
Before that, the DMA channel number was implicitly initialized to zero
because the backing store was allocated with devm_kzalloc(). When the
init code was rewritten, that implicit initialization was lost, and gcc
rightfully complains about an uninitialized variable being used.

This reverts commit bfd8d3f23b.
It turns out that this flushes things much too aggressiverly, and causes
lines to break up when the system logger races with new continuation
lines being printed.
There's a pending patch to make printk() flushing much more
straightforward, but it's too invasive for 4.9, so in the meantime let's
just not make the system message logging flush continuation lines.
They'll be flushed by the final newline anyway.

We get the following build error from UM Linux after adding
an entry to drivers/iio/gyro/Kconfig that issues "select I2C_MUX":
ERROR: "devm_ioremap_resource"
[drivers/i2c/muxes/i2c-mux-reg.ko] undefined!
ERROR: "of_address_to_resource"
[drivers/i2c/muxes/i2c-mux-reg.ko] undefined!
It appears that the I2C mux core code depends on HAS_IOMEM
for historical reasons, while CONFIG_I2C_MUX_REG does *not*
have a direct dependency on HAS_IOMEM.
This creates a situation where a allyesconfig or allmodconfig
for UM Linux will select I2C_MUX, and will implicitly enable
I2C_MUX_REG as well, and the compilation will fail for the
register driver.
Fix this up by making I2C_MUX_REG depend on HAS_IOMEM and
removing the dependency from I2C_MUX.

While testing nvme-rdma with the spdk nvmf target over iw_cxgb4, I
configured the target (mistakenly) to generate an error creating the
NVMF IO queues. This resulted a "Invalid SQE Parameter" error sent back
to the host on the first IO queue connect:
[ 9610.928182] nvme nvme1: queue_size 128 > ctrl maxcmd 120, clamping down
[ 9610.938745] nvme nvme1: creating 32 I/O queues.
So nvmf_connect_io_queue() returns an error to
nvmf_connect_io_queue() / nvmf_connect_io_queues(), and that
is returned to nvme_rdma_create_io_queues(). In the error path,
nvmf_rdma_create_io_queues() frees the queue tagset memory _before_
stopping and freeing the IB queues, which causes yet another
touch-after-free crash due to SQ CQEs being flushed after the ib_cqe
structs pointed-to by the flushed WRs have been freed (since they are
part of the nvme_rdma_request struct).
The fix is to stop and free the queues in nvmf_connect_io_queues()
if there is an error connecting any of the queues.

This is a static checker warning, not something I'm desperately
concerned about. But snprintf() returns the number of bytes that
would have been copied if there were space. We really care about the
number of bytes that actually were copied so we should use scnprintf()
instead.
It probably won't overrun, and in that case we may as well just use
sprintf() but these sorts of things make static checkers and code
reviewers happier.

efx_copy_channel() doesn't correctly clear the napi_hash related state.
This means that when napi_hash_add is called for that channel nothing is
done, and we are left with a copy of the napi_hash_node from the old
channel. When we later call napi_hash_del() on this channel we have a
stale napi_hash_node.
Corruption is only seen when there are multiple entries in one of the
napi_hash lists. This is made more likely by having a very large number
of channels. Testing was carried out with 512 channels - 32 channels on
each of 16 ports.
This failure typically appears as protection faults within napi_by_id()
or napi_hash_add(). efx_copy_channel() is only used when tx or rx ring
sizes are changed (ethtool -G).

"The megaraid_sas patch in here fixes a major regression in the last
fix set that made all megaraid_sas cards unusable. It turns out no-one
had actually tested such an "obvious" fix, sigh. The fix for the fix
has been tested ...
The next most serious is the vmw_pvscsi abort problem which basically
means that aborts don't work on the vmware paravirt devices and error
handling always escalates to reset.
The rest are an assortment of missed reference counting in certain
paths and corner case bugs that show up on some architectures"

anything in the core framework here, just driver fixes. There's a boot fix for
Samsung devices and a safety measure for qoriq to prevent CPUs from running too
fast. There's also a fix for i.MX6Q to properly handle audio clock rates. We
also have some "that's obviously wrong" fixes like bad NULL pointer checks in
the MPP driver and a poor usage of __pa in the xgene clk driver that are fixed
here.

The DVB binding schema at the DVB core assumes that the frontend is a
separate driver. Faling to do that causes OOPS when the module is
removed, as it tries to do a symbol_put_addr on an internal symbol,
causing craches like:

Commit bc29131ecb10 ("[media] gp8psk: don't do DMA on stack") fixed the
usage of DMA on stack, but the memcpy was wrong for gp8psk_usb_in_op().
Fix it.

The device's neighbour table is periodically dumped in order to update
the kernel about active neighbours. A single dump session may span
multiple queries, until the response carries less records than requested
or when a record (can contain up to four neighbour entries) is not full.
Current code stops the session when the number of returned records is
zero, which can result in infinite loop in case of high packet rate.
Fix this by stopping the session according to the above logic.

When binding port to a newly created span entry, its refcount is
initialized to zero even though it has a bound port. That leads
to unexpected behaviour when the user tries to delete that port
from the span entry.
Fix this by initializing the reference count to 1.
Also add a warning to put function.

====================
bnxt_en: 2 bug fixes.
Bug fixes in bnxt_setup_tc() and VF vitual link state.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
If the physical link is down and the VF virtual link is set to "enable",
the current code does not always work. If the link is down but the
cable is attached, the firmware returns LINK_SIGNAL instead of
NO_LINK. The current code is treating LINK_SIGNAL as link up.
The fix is to treat link as down when the link_status != LINK.
