A DASD device consists of the device itself and a discipline with a
corresponding private structure. These fields are set up during online
processing right after the device is created and before it is processed by
the state machine and made available for I/O.
During offline processing the discipline pointer and the private data gets
freed within the state machine and without protection of the existing
reference count. This might lead to a kernel panic because a function might
have taken a device reference and accesses the discipline pointer and/or
private data of the device while this is already freed.
Fix by freeing the discipline pointer and the private data after ensuring
that there is no reference to the device left.

Internal I/O is processed by the _sleep_on_function which might wait for a
device to get operational. During offline processing this will never happen
and therefore the refcount of the device will not drop to zero and the
offline processing blocks as well.
Fix by letting requests fail in the _sleep_on function during offline
processing. No further handling of the requests is necessary since this is
internal I/O and the device is thrown away afterwards.

When initially connected via USB the Sixaxis isn't fully initialized
until the PS logo button is pressed and won't send any input reports
nor will any state set by output reports be retained.
This adds a 'defer_initialization' flag to the sony_sc struct which,
when set, will delay sending any output reports until the first input
report has arrived. This flag is used with the USB Sixaxis to ensure
that any state sent will persist since, until the PS button is pushed,
any changes sent to the controller via an output report will be lost
after a couple of seconds.
The initial state of the controller is still configured at the time
of the initial connection and won't be internally modified after that,
so any state set by the user between that time and the recepit of the
first input report won't be lost.

Some USB-only devices which masquerade as Sixaxis controllers report the
same generic Bluetooth address for all hardware when queried via the HID
report. This causes these devices to be wrongly rejected as duplicates
when more than one is connected at once.
This introduces a connection type comparison when checking for duplicates
and only rejects the newly connected device if the existing matching
device is connected using a different connection protocol.
The results of the connection type comparison are also used when
registering power supply info as the device Bluetooth address is used
as the unique identifier string. In cases where more than one valid
device has the same Bluetooth address the device ID is now appended
to the power supply name string to avoid name collisions when
registering the power supply information.

In some places, dump_backtrace() is called with a NULL tsk parameter,
e.g. in bug_handler() in arch/arm64, or indirectly via show_stack() in
core code. The expectation is that this is treated as if current were
passed instead of NULL. Similar is true of unwind_frame().
Commit a80a0eb70c ("arm64: make irq_stack_ptr more robust") didn't
take this into account. In dump_backtrace() it compares tsk against
current *before* we check if tsk is NULL, and in unwind_frame() we never
set tsk if it is NULL.
Due to this, we won't initialise irq_stack_ptr in either function. In
dump_backtrace() this results in calling dump_mem() for memory
immediately above the IRQ stack range, rather than for the relevant
range on the task stack. In unwind_frame we'll reject unwinding frames
on the IRQ stack.
In either case this results in incomplete or misleading backtrace
information, but is not otherwise problematic. The initial percpu areas
(including the IRQ stacks) are allocated in the linear map, and dump_mem
uses __get_user(), so we shouldn't access anything with side-effects,
and will handle holes safely.
This patch fixes the issue by having both functions handle the NULL tsk
case before doing anything else with tsk.

The OPP framework allows each OPP to set a opp-supported-hw property
which provides values that are matched against supported_hw values
provided by the platform to limit support for certain OPPs on specific
hardware. Currently, if the platform does not set supported_hw values,
all OPPs are interpreted as supported, even if they have provided their
own opp-supported-hw values.
If an OPP has provided opp-supported-hw, it is indicating that there is
some specific hardware configuration it is supported by. These constraints
should be honored, and if no supported_hw has been provided by the
platform, there is no way to determine if that OPP is actually supported,
so it should be marked as not supported.

Change predecrement compare to post decrement compare to avoid an
unsigned integer wrap-around comparisomn when decrementing in the while
loop.
For example, if the debugfs_create_file() fails when 'i' is zero, the
current situation will predecrement 'i' in the while loop, wrapping 'i' to
the maximum signed integer and cause multiple out of bounds reads on
dfs_fls[i].d as the loop interates to zero.

I stumbled over a new warning during randconfig testing,
with CONFIG_BPF_SYSCALL disabled:
drivers/net/ethernet/netronome/nfp/nfp_net_offload.c: In function 'nfp_net_bpf_offload':
drivers/net/ethernet/netronome/nfp/nfp_net_offload.c:263:3: error: '*((void *)&res+4)' may be used uninitialized in this function [-Werror=maybe-uninitialized]
drivers/net/ethernet/netronome/nfp/nfp_net_offload.c:263:3: error: 'res.n_instr' may be used uninitialized in this function [-Werror=maybe-uninitialized]
As far as I can tell, this is a false positive caused by the compiler
getting confused about a function that is partially inlined, but it's
easy to avoid while improving the code:
The nfp_bpf_jit() stub helper for that configuration is unusual as it
is defined in a header file but not marked 'static inline'. By moving
the compile-time check into the caller using the IS_ENABLED() macro,
we can remove that stub and simplify the nfp_net_bpf_offload_prepare()
function enough to unconfuse the compiler.
