ALSA: rawmidi: Take buffer refcount while draining output
Although snd_rawmidi_drain_output() may take some long time, it has no
protection and intrusive operations like the buffer resize may happen
meanwhile. For making the operation a bit more robust, this patch
takes the buffer refcount for blocking the buffer resize.
Also, as this function is exported, in theory, it might be called
asynchronously from the stream open/close state. For avoiding the
missing refcount, now the close call checks the buffer refcount, too.

ALSA: rawmidi: Check stream state at exported functions
The rawmidi interface provides some exported functions to be called
from outside, and currently there is no state check for those calls
whether the stream is properly opened and running. Although such an
invalid call shouldn't happen, but who knows.
This patch adds the proper rawmidi stream state checks with spinlocks
for avoiding unexpected accesses when such exported functions are
called in an invalid state. After this patch, with the
substream->opened and substream->runtime are always tied and
guaranteed to be set under substream->lock.

ALSA: rawmidi: Take open_mutex around parameter changes
The input/output parameter changes are pretty intrusive, possibly
involving with the buffer resizing operation. Hence those should be
performed exclusively; otherwise some ugly race could happen.
This patch puts the existing open_mutex for snd_rawmidi_input_params()
and *_output_params() for protecting the concurrent calls. Since
those are exported, it's also meant for hardening from the external
calls, too.

a substream is accessed from the outside, as the runtime creation
might be racy with the external calls. As a first step for hardening,
move the spinlock from snd_rawmidi_runtime to snd_rawmidi_substream.
This patch just replaces the lock calls, no real functional change is
put yet.

Set #pwm-cells to the default 3 to gain access to the parameter
which allows inverting the PWM signal. This is useful to specify
a backlight which has its highest brightness at 0.
With the change to use the PWM with inverted polarity the PWM signal
is inverted to how it was before this patch.
This changes the meaning of the values in the brightness-levels
property. I.e. the duty-cycle changes from x/255 to (255-x)/255.

jump from 0 to 127 duty cycle, the other 6 steps will then be

random.c ratelimits how much it warns about uninitialized urandom reads
using __ratelimit(). When the RNG is finally initialized, it prints the
number of missed messages due to ratelimiting.
It has been this way since that functionality was introduced back in
2018. Recently, cc1e127bfa95 ("random: remove ratelimiting for in-kernel
unseeded randomness") put a bit more stress on the urandom ratelimiting,
which teased out a bug in the implementation.
Specifically, when under pressure, __ratelimit() will print its own
message and reset the count back to 0, making the final message at the
end less useful. Secondly, it does so as a pr_warn(), which apparently
is undesirable for people's CI.
Fortunately, __ratelimit() has the RATELIMIT_MSG_ON_RELEASE flag exactly
for this purpose, so we set the flag.

random: schedule mix_interrupt_randomness() less often
It used to be that mix_interrupt_randomness() would credit 1 bit each
time it ran, and so add_interrupt_randomness() would schedule mix() to
run every 64 interrupts, a fairly arbitrary number, but nonetheless
considered to be a decent enough conservative estimate.
Since e3e33fc2ea7f ("random: do not use input pool from hard IRQs"),
mix() is now able to credit multiple bits, depending on the number of
calls to add(). This was done for reasons separate from this commit, but
it has the nice side effect of enabling this patch to schedule mix()
less often.
Currently the rules are:
a) Credit 1 bit for every 64 calls to add().
b) Schedule mix() once a second that add() is called.
c) Schedule mix() once every 64 calls to add().
Rules (a) and (c) no longer need to be coupled. It's still important to
have _some_ value in (c), so that we don't "over-saturate" the fast
pool, but the once per second we get from rule (b) is a plenty enough
baseline. So, by increasing the 64 in rule (c) to something larger, we
avoid calling queue_work_on() as frequently during irq storms.
This commit changes that 64 in rule (c) to be 1024, which means we
schedule mix() 16 times less often. And it does *not* need to change the
64 in rule (a).
