The DMA channel of firmware command doesn't use TX WD (WiFi descriptor), so
don't need to consider number of TX WD as factor of TX resource. Otherwise,
during pause state (a transient state to switch to/from low power mode)
firmware commands could be dropped and driver throws warnings suddenly:
rtw89_8852ce 0000:04:00.0: no tx fwcmd resource
rtw89_8852ce 0000:04:00.0: failed to send h2c
The case we met is that driver sends RSSI strength of firmware command at
RX path that could be running concurrently with switching low power mode.
The missing of this firmware command doesn't affect user experiences,
because the RSSI strength will be updated again after a while.
The DMA descriptors of normal packets has three layers like:
+-------+
| TX BD | (*n elements)
+-------+
|
| +-------+
+-> | TX WD | (*m elements)
+-------+
|
| +--------+
+-> | SKB |
+--------+
And, firmware command queue (TXCH 12) is a special queue that has only
two layers:
+-------+
| TX BD | (*n elements)
+-------+
|
| +------------------+
+-> | firmware command |

In commit b4ccace878 ("btrfs: refactor submit_compressed_extents()"), if
an async extent compressed but failed to find enough space, we changed
from falling back to an uncompressed write to just failing the write
altogether. The principle was that if there's not enough space to write
the compressed version of the data, there can't possibly be enough space
to write the larger, uncompressed version of the data.
However, this isn't necessarily true: due to fragmentation, there could
be enough discontiguous free blocks to write the uncompressed version,
but not enough contiguous free blocks to write the smaller but
unsplittable compressed version.
This has occurred to an internal workload which relied on write()'s
return value indicating there was space. While rare, it has happened a
few times.
Thus, in order to prevent early ENOSPC, re-add a fallback to
uncompressed writing.

When btrfs scrub finds an error, it reads mirrors to find correct data. If
all the errors are fixed, sctx->error_bitmap is cleared for the stripe
range. However, in the zoned mode, it runs relocation to repair scrub
errors when the bitmap is *not* empty, which is a flipped condition.
Also, it runs the relocation even if the scrub is read-only. This was
missed by a fix in commit 1f2030ff6e ("btrfs: scrub: respect the
read-only flag during repair").
The repair is only necessary when there is a repaired sector and should be
done on read-write scrub. So, tweak the condition for both regular and
zoned case.

Add support for a new SPMI vibrator module which is very similar
to the vibrator module inside PM8916 but has a finer drive voltage
step and different output voltage range, its drive level control
is expanded across 2 registers. The vibrator module can be found
in following Qualcomm PMICs: PMI632, PM7250B, PM7325B, PM7550BA.

Currently, vibrator control register addresses are hard coded,
including the base address and offsets, it's not flexible to
support new SPMI vibrator module which is usually included in
different PMICs with different base address. Refactor it by using
the base address defined in devicetree.

KEY_TYPE_error is left behind when we have to delete all pointers in an
extent in fsck; it allows errors to be correctly returned by reads
later.
