Previously, we account reserved blocks and compressed blocks into
@compr_blocks, then, f2fs_i_compr_blocks_update(,compr_blocks) will
update i_compr_blocks incorrectly, fix it.
Meanwhile, for the case all blocks in cluster were reserved, fix to
update dn->ofs_in_node correctly.

[ Upstream commit f24ba846133d0edec785ac6430d4daf6e9c93a09 ]
The "Downstream Port Containment related Enhancements" ECN of Jan 28, 2019
(document 12888 below), defined the EDR_PORT_DPC_ENABLE_DSM function with
Revision ID 5 with Arg3 being an integer. But when the ECN was integrated
into PCI Firmware r3.3, sec 4.6.12, it was defined as Revision ID 6 with
Arg3 being a package containing an integer.
The implementation in acpi_enable_dpc() supplies a package as Arg3 (arg4 in
the code), but it previously specified Revision ID 5. Align this with PCI
Firmware r3.3 by using Revision ID 6.
If firmware implemented per the ECN, its Revision 5 function would receive
a package as Arg3 when it expects an integer, so acpi_enable_dpc() would
likely fail. If such firmware exists and lacks a Revision 6 function that
expects a package, we may have to add support for Revision 5.

IRQ_DOMAIN is a hidden (not user visible) symbol. Users cannot set
it directly thru "make *config", so drivers should select it instead
of depending on it if they need it.
Relying on it being set for a dependency is risky.
Consistently using "select" or "depends on" can also help reduce
Kconfig circular dependency issues.
Therefore, change EXTCON_MAX8997's use of "depends on" for
IRQ_DOMAIN to "select".

ui_browser__show() is capturing the input title that is stack allocated
memory in hist_browser__run().
Avoid a use after return by strdup-ing the string.
Committer notes:
Further explanation from Ian Rogers:
My command line using tui is:
$ sudo bash -c 'rm /tmp/asan.log*; export
ASAN_OPTIONS="log_path=/tmp/asan.log"; /tmp/perf/perf mem record -a
sleep 1; /tmp/perf/perf mem report'
I then go to the perf annotate view and quit. This triggers the asan
error (from the log file):

hist_browser__run isn't on the stack so the asan error looks legit.

anyway.

[ Upstream commit e3b3afd34d84efcbe4543deb966b1990f43584b8 ]
The always-running (from linux,wdt-gpio.yaml) is abused by the BD9576
watchdog driver. It's defined meaning is "the watchdog is always running
and can not be stopped". The BD9576 watchdog driver has implemented it
as "start watchdog when loading the module and prevent it from being
stopped".
Furthermore, the implementation does not set the WDOG_HW_RUNNING when
enabling the watchdog due to the "always-running" at module loading.
This will end up resulting a watchdog timeout if the device is not
opened.
The culprit was pointed out by Guenter, discussion can be found from

[ Upstream commit b7c0e1ecee403a43abc89eb3e75672b01ff2ece9 ]
The current implementation of the fpga region assumes that the low-level
module registers a driver for the parent device and uses its owner pointer
to take the module's refcount. This approach is problematic since it can
lead to a null pointer dereference while attempting to get the region
during programming if the parent device does not have a driver.
To address this problem, add a module owner pointer to the fpga_region
struct and use it to take the module's refcount. Modify the functions for
registering a region to take an additional owner module parameter and
rename them to avoid conflicts. Use the old function names for helper
macros that automatically set the module that registers the region as the
owner. This ensures compatibility with existing low-level control modules
and reduces the chances of registering a region without setting the owner.
Also, update the documentation to keep it consistent with the new interface
for registering an fpga region.
