Since we have the MST feature enabled and Pin-Port mux for user to
select the converter routing, multiple port mapping to same converter
needs to be supported.
To support multiple port mapped to same converter following changes are
done for this:.
o Add port list to pcm, so that multiple ports can be mapped to a PCM.
o Jack reporting in case where multiple port are attached to same PCM.
o Change hdac_hdmi_get_port_from_cvt(), channel_map, remove functions
to parse through all ports mapped to same the PCM.

To enable stream on a specific port of a MST capable pin, the port
needs to be selected before we configure the pin widget verb.
When port is selected, all the pin widget verb controlling the sink
device operation will be directed to selected port. So add port
selection before configuring the pin widget verb.

The ELD notification can be received asynchronously from the graphics
side and this may happen just at the moment the sound driver is
initializing and notification will be missed. Similarly at system
resume, the notification is ignored as the ELD and connection states
are updated in anyway at the end of the resume.
So check the jack status in boot/resume by querying the port presence
based on pin caps and report the jack status.

Enabling both DEBUG_WX=y and KASAN=y options significantly increases
boot time (dozens of seconds at least).
KASAN fills kernel page tables with repeated values to map several
TBs of the virtual memory to the single kasan_zero_page:
kasan_zero_pud ->
kasan_zero_pmd->
kasan_zero_pte->
kasan_zero_page
So, the page table walker used to find W+X mapping check the same
kasan_zero_p?d page table entries a lot more than once.
With patch pud walker will skip the pud if it has the same value as
the previous one . Skipping done iff we search for W+X mappings,
so this optimization won't affect the page table dump via debugfs.
This dropped time spend in W+X check from ~30 sec to reasonable 0.1 sec:
Before:
[ 4.579991] Freeing unused kernel memory: 1000K
[ 35.257523] x86/mm: Checked W+X mappings: passed, no W+X pages found.
After:
[ 5.138756] Freeing unused kernel memory: 1000K
[ 5.266496] x86/mm: Checked W+X mappings: passed, no W+X pages found.

When there is no status bit, it is possible for the clock enable/disable

In qspi_transfer_in(), when receiving the last n (or len) bytes of data,
one bogus byte was written in the receive buffer.
This code leads to a buffer overflow.
"jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found
at 0x03b40000: 0x1900 instead
jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found
at 0x03b40004: 0x000c instead"
The error message above happens when trying to mount, unmount,
and remount a jffs2-formatted device.
This patch removed the bogus write to fixes: 3be09bec42
"spi: rspi: supports 32bytes buffer for DUAL and QUAD"
And here is Geert's comment:
"spi: rspi: Fix bogus received byte in qspi_transfer_in()
When there are less than QSPI_BUFFER_SIZE remaining bytes to be received,
qspi_transfer_in() writes one bogus byte in the receive buffer, possibly
leading to a buffer overflow.
This can be reproduced by mounting, unmounting, and remounting a
jffs2-formatted device, causing lots of warnings like:
"jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found
at 0x03b40000: 0x1900 instead"
Remove the bogus write to fix this. "

After commit 66d228a2bf ("regulator: core: Don't use regulators as
supplies until the parent is bound"), input supplies aren't resolved
if the input supplies parent device has not been bound. This prevent
regulators to hold an invalid reference if its supply parent device
driver probe is deferred.
But this causes issues on some boards where a PMIC's regulator use as
input supply a regulator from another PMIC whose driver is registered
after the driver for the former.
In this case the regulators for the first PMIC will fail to resolve
input supplies on regulators registration (since the other PMIC wasn't
probed yet). And when the core attempts to resolve again latter when
the other PMIC registers its own regulators, it will fail again since
the parent device isn't bound yet.
This will cause some parent supplies to never be resolved and wrongly
be disabled on boot due taking them as unused.
To solve this problem, also attempt to resolve the pending regulators
input supplies before disabling the unused regulators.

Currently this module needs to be manually configured by COMEDI
userspace tool before the test waveform can be read by a COMEDI
compatible application.
This patch adds auto-configuration capability and makes it the default
loading option. This is achieved by creating a device during init
to stand in for a real hardware device. This allows comedi_auto_config()
to perform auto-configuration. With this patch, the test waveform can
be read by a COMEDI compatible application without needing manual
configuration.
Previous behaviour is still selectable via module loading parameter.
Module loading without passing any parameter will default to
auto-configuration with the same default waveform amplitude and
period values. For auto-configuration, different amplitude and
period values can be set via module loading parameters.
Tested on Xubuntu 16.04 using Xoscope ver: 2.0 which is available
in the Ubuntu repository. Xoscope is a COMEDI compatible digital
oscilloscope application. For manual configuration, only module
loading/unloading is tested.
Here are the truncated dmesg output.
[sudo modprobe comedi_test]
comedi_test: 1000000 microvolt, 100000 microsecond waveform attached
driver 'comedi_test' has successfully auto-configured 'comedi_test'.
[sudo modprobe comedi_test amplitude=2500000 period=150000]
comedi_test: 2500000 microvolt, 150000 microsecond waveform attached
driver 'comedi_test' has successfully auto-configured 'comedi_test'.
[sudo modprobe comedi_test noauto=1]
comedi_test: module is from the staging directory, the quality is unknown,
you have been warned.
For those without an actual hardware, the comedi_test module
is as close as one can get to test the COMEDI system.
Having both auto and manual configuration capability will broaden
the test function of this module.
Hopefully this will make it easier for people to check out the
COMEDI system and contribute to its development.
