Commit b3a706014e (libata: Add a
drivers/ide style DMA disable) neglected to remove the line in
ata_do_set_mode() it has obviously made useless/duplicated. Do this
now, and make a line added back then wrapped properly...

The only high-level SCSI driver that currently implements runtime PM is
sd, and sd treats runtime suspend exactly the same as the SUSPEND and
HIBERNATE stages of system sleep, but not the same as the FREEZE stage.
Therefore, when entering the SUSPEND or HIBERNATE stages of system
sleep, we can skip the callback to the driver if the device is already
in runtime suspend. When entering the FREEZE stage, however, we should
first issue a runtime resume. The overhead of doing this is
negligible, because a suspended drive would be spun up during the THAW
stage of hibernation anyway.

With previous change, now the ata port runtime suspend will happen as:
disk suspend --> scsi target suspend --> scsi host suspend --> ata port
suspend
ata port(parent device) suspend need to schedule scsi EH which will resume
scsi host(child device). Then the child device resume will in turn make
parent device resume first. This is kind of recursive.
This patch adds a new flag Scsi_Host::eh_noresume.
ata port will set this flag to skip the runtime PM calls on scsi host.

Currently, the device tree of ata port and scsi host looks as below,
/sys/devices/pci0000:00/0000:00:1f.2 (ahci controller)
|-- ata1 (ata port)
|-- host0 (scsi host)
|-- target0:0:0 (scsi target)
|-- 0:0:0:0 (disk)
This patch makes ata port as parent device of scsi host, then it becomes
/sys/devices/pci0000:00/0000:00:1f.2 (ahci controller)
|-- ata1 (ata port)
|-- host0 (scsi host)
|-- target0:0:0 (scsi target)
|-- 0:0:0:0 (disk)
With this change, the ata port runtime PM is easier.
For example, the ata port runtime suspend will happen as,
disk suspend --> scsi target suspend --> scsi host suspend --> ata port
suspend.

This is another attempt at fixing the same problem that 270dac35c2
(libata: ahci_start_engine compliant to AHCI spec) tried to solve.
Unfortunately, 270dac35c2 created regressions for a lot more common
controllers and got reverted.
This specific AHCI IP block becomes a brick if the DMA engine is
started while DRQ is set. It is not possible to avoid the condition
completely but the most common occurrence is caused by spurious use of
ahci_start_engine() from ahci_start_port() during init sequence.
DMA engine is started after both soft and hard resets and
ahci_start_port() is always followed by resets, so there is no reason
to start DMA engine from ahci_start_port().
This patch removes ahci_start_engine() invocation from
ahci_start_port(). This change makes failure path of
ahci_port_suspend() leave engine stopped without following resets.
This is resolved by replacing ahci_start_port() call with
ata_port_freeze() which forces resets afterwards, which is the better
behavior anyway.

Some SoCs have a timer block enable controlled through the DSCR registers.
There is a problem in the timer64 driver initialization where the code
accesses a timer register to get the divisor used to calculate timer clock

place, an exception is generated. This patch makes sure that the timer block

A malicious USB device may feed in carefully crafted min/max/res values,
so that the inner loop in parse_uac2_sample_rate_range() could run for
a long time or even never terminate, e.g., given max = INT_MAX.
Also nr_rates could be a large integer, which causes an integer overflow
in the subsequent call to kmalloc() in parse_audio_format_rates_v2().
Thus, kmalloc() would allocate a smaller buffer than expected, leading
to a memory corruption.
To exploit the two vulnerabilities, an attacker needs physical access
to the machine to plug in a malicious USB device.
This patch makes two changes.
1) The type of "rate" is changed to unsigned int, so that the loop could
stop once "rate" is larger than INT_MAX.
2) Limit nr_rates to 1024.
