The I2S controller can use the external clock as reference clock with
master mode. But based on different hardware or software design, this
external clock might be needed or not needed.
So the external input pin can be an independent pinctrl group, and the
card driver can decice to get it or not.

The I2S controller can output mclk to external audio codec. But by
hardware design, some codecs need mclk and some codecs do not need
mclk. So the mclk pin can be an independent pinctrl group, and the
card driver can get it or not based on boards.

update_insn_emulation_mode() returns 0 on success, so we should be
treating any non-zero values as failure, rather than the other way
around. Otherwise, writes to the sysctl file controlling the emulation
are ignored and immediately rolled back.

The xpad wireless endpoint is not a bulk endpoint on my devices, but
rather an interrupt one, so the USB core complains when it is submitted.
I'm guessing that the author really did mean that this should be an
interrupt urb, but as there are a zillion different xpad devices out
there, let's cover out bases and handle both bulk and interrupt
endpoints just as easily.

If for some reason we are unable to shut it down in orderly fashion
(kernel is stuck holding a lock or similar), then hardware TSHUT will
reset it.
If the temperature is over 95C over a period of time the thermal shutdown

or notify the PMIC via a GPIO. This should be set in the specific board.

ping_lookup() may return a wrong sock if sk_buff's and sock's protocols
dont' match. For example, sk_buff's protocol is ETH_P_IPV6, but sock's
sk_family is AF_INET, in that case, if sk->sk_bound_dev_if is zero, a wrong
sock will be returned.
the fix is to "continue" the searching, if no matching, return NULL.

af_packet produces lots of these:
net/packet/af_packet.c:384:39: warning: incorrect type in return expression (different modifiers)
net/packet/af_packet.c:384:39: expected struct page [pure] *
net/packet/af_packet.c:384:39: got struct page *
this seems to be because sparse does not realize that _pure
refers to function, not the returned pointer.
Tweak code slightly to avoid the warning.

scsi_reset_provider already manually runs all queues for the given host,
so it doesn't need the scsi_run_queues call from it, and it doesn't need
a reference on the device because it's synchronous.
So let's just call scsi_put_command directly and avoid the device reference
dance to simplify the code.

On PCscsi, the FENAB configuration also enables 24-bit DMA
transfer lengths (and provides the chip id in TCHI after reset).
We want to be able to enable this parameter from the DMA driver.
Check if the caller of scsi_esp_register provided a value for esp->config2.
If this is the case, assume this is not an ESP100, skip the detection
phase and leave esp->config2 untouched. It will be used in esp_reset_esp.

Using DMA for command submission has the drawback that it might
generate additional DMA completion interrupts after the command
has been submitted to the device.
Additionally the am53c974 has a design flaw causing it
to generate spurious interrupts even though DMA completion
interrupts are not enabled.
This can be avoided by using the FIFO for command submission.
