The IMR was assumed to be preserved when suspending to S4 and S5
states, but community reports invalidate that assumption, the hardware
seems to be powered off and the IMR memory content cleared.
Make sure regular boot with firmware download is used for S4 and S5.

Commit 288fad2f71fa ("ASoC: SOF: Intel: hda: add quirks for HDAudio DMA position information")
modified the PCM path only, but left the compressed data patch using an

The "wlf,spkvdd-ena" GPIO needed by the bytcr_wm5102 driver
is made available through a gpio-lookup table.
This gpio-lookup table is registered by drivers/mfd/arizona-spi.c, which
may get probed after the bytcr_wm5102 driver.
If the gpio-lookup table has not registered yet then the gpiod_get()
will return -ENOENT. Treat -ENOENT as -EPROBE_DEFER to still keep
things working in this case.

Currently in slim_rx_mux_put, an RX channel gets added to a new list
even if it is already in one. This can mess up links and make either
it, the new list head, or both, get linked to the wrong entries.
This can cause an entry to link to itself which in turn ends up
making list_for_each_entry in other functions loop infinitely.
To avoid issues, always remove the RX channel from any list it's in
before adding it to a new list.

The .set_jack_detect() codec component callback is invoked during card
registration, which happens when the machine driver is probed.
The issue is that this callback can race with the bus suspend/resume,
and IO timeouts can happen. This can be reproduced very easily if the
machine driver is 'blacklisted' and manually probed after the bus
suspends. The bus and codec need to be re-initialized using pm_runtime
helpers.
Previous contributions tried to make sure accesses to the bus during
the .set_jack_detect() component callback only happen when the bus is
active. This was done by changing the regcache status on a component
remove. This is however a layering violation, the regcache status
should only be modified on device probe, suspend and resume. The
component probe/remove should not modify how the device regcache is
handled. This solution also didn't handle all the possible race
conditions, and the RT700 headset codec was not handled.
This patch tries to resume the codec device before handling the jack
initializations. In case the codec has not yet been initialized,
pm_runtime may not be enabled yet, so we don't squelch the -EACCES
error code and only stop the jack information. When the codec reports
as attached, the jack initialization will proceed as usual.

Realtek headset codec drivers typically check if the card is
instantiated before proceeding with the jack detection.
The rt700, rt711 and rt711-sdca are however missing a check on the

driver bind/unbind tests.

of connection setup flags, and in the process causes odd problems when
it converts between a bitmap and just the regular values of said bits.
It's completely pointless to do things like bitmap_to_arr32() to convert
a bitmap into a u32. It shoudln't have been a bitmap in the first
place. The reason to use bitmaps is if you have arbitrary number of
bits you want to manage (not two!), or if you rely on the atomicity
guarantees of the bitmap setting and clearing.
The code could use an "atomic_t" and use "atomic_or/andnot()" to set and
clear the bit values, but considering that it then copies the bitmaps
around with "bitmap_to_arr32()" and friends, there clearly cannot be a
lot of atomicity requirements.
So just use a regular integer.
In the process, this avoids the warnings about erroneous use of
bitmap_from_u64() which were triggered on 32-bit architectures when
conversion from a u64 would access two words (and, surprise, surprise,
only one word is needed - and indeed overkill - for a 2-bit bitmap).
That was always problematic, but the compiler seems to notice it and
warn about the invalid pattern only after commit 0a97953fd221 ("lib: add
bitmap_{from,to}_arr64") changed the exact implementation details of
'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.

It used to grab an extra reference to struct file rather than
just transferring to caller the one it had removed from descriptor
table. New variant doesn't, and callers need to be adjusted.
