This tag includes two fixes. The first one, in the Cadence driver
seen in Qemu, prevents unintentional FIFO clearing at the
beginning of a transaction. The second fix, in the SynQuacer,
ensures proper error handling during clock get, prepare, and
enable operations by using the devm_clk_get_enabled() helper.

Merge tag 'bcachefs-2024-05-19' of https://evilpiepirate.org/git/bcachefs

Pull bcachefs updates from Kent Overstreet:

- More safety fixes, primarily found by syzbot

- Run the upgrade/downgrade paths in nochnages mode. Nochanges mode is
primarily for testing fsck/recovery in dry run mode, so it shouldn't
change anything besides disabling writes and holding dirty metadata
in memory.

The idea here was to reduce the amount of activity if we can't write
anything out, so that bringing up a filesystem in "super ro" mode
would be more lilkely to work for data recovery - but norecovery is
the correct option for this.

- btree_trans->locked; we now track whether a btree_trans has any btree
nodes locked, and this is used for improved assertions related to
trans_unlock() and trans_relock(). We'll also be using it for
improving how we work with lockdep in the future: we don't want
lockdep to be tracking individual btree node locks because we take
too many for lockdep to track, and it's not necessary since we have a
cycle detector.

- Trigger improvements that are prep work for online fsck

- BTREE_TRIGGER_check_repair; this regularizes how we do some repair
work for extents that goes with running triggers in fsck, and fixes
some subtle issues with transaction restarts there.

- bch2_snapshot_equiv() has now been ripped out of fsck.c; snapshot
equivalence classes are for when snapshot deletion leaves behind
redundant snapshot nodes, but snapshot deletion now cleans this up
right away, so the abstraction doesn't need to leak.

- Improvements to how we resume writing to the journal in recovery. The
code for picking the new place to write when reading the journal is
greatly simplified and we also store the position in the superblock
for when we don't read the journal; this means that we preserve more
of the journal for list_journal debugging.

- Improvements to sysfs btree_cache and btree_node_cache, for debugging
memory reclaim.

- We now detect when we've blocked for 10 seconds on the allocator in
the write path and dump some useful info.

- Safety fixes for devices references: this is a big series that
changes almost all device lookups to properly check if the device
exists and take a reference to it.

Previously we assumed that if a bkey exists that references a device
then the device must exist, and this was enforced in .invalid
methods, but this was incorrect because it meant device removal
relied on accounting being correct to not leave keys pointing to
invalid devices, and that's not something we can assume.

Getting the "pointer to invalid device" checks out of our .invalid()
methods fixes some long standing device removal bugs; the only
outstanding bug with device removal now is a race between the discard
path and deleting alloc info, which should be easily fixed.

- The allocator now prefers not to expand the new
member_info.btree_allocated bitmap, meaning if repair ever requires
scanning for btree nodes (because of a corrupt interior nodes) we
won't have to scan the whole device(s).

- New coding style document, which among other things talks about the
correct usage of assertions

bcachefs: journal seq blacklist gc no longer has to walk btree

Since btree_ptr_v2, we no longer require the journal seq blacklist table
for skipping blacklisted bsets (btree node entries); the pointer to a
given node indicates how much data is present.

Therefore there's no longer any need for journal seq blacklist gc to
walk the btree - we can prune entries older than journal last_seq.

ASoC: Updates for v6.10

This is a very big update, in large part due to extensive work the Intel
people have been doing in their drivers though it's also been busy
elsewhere. There's also a big overhaul of the DAPM documentation from
Luca Ceresoli arising from the work he did putting together his recent
ELC talk, and he also contributed a new tool for visualising the DAPM
state.

- A new tool dapm-graph for visualising the DAPM state.
- Substantial fixes and clarifications for the DAPM documentation.
- Very large updates throughout the Intel audio drivers.
- Cleanups of accessors for driver data, module labelling, and for
constification.
- Modernsation and cleanup work in the Mediatek drivers.
- Several fixes and features for the DaVinci I2S driver.
- New drivers for several AMD and Intel platforms, Nuvoton NAU8325,
Rockchip RK3308 and Texas Instruments PCM6240.
