While working with this controller I figured out a couple of small
issues which I propose to fix. They are not super impacting, but I
believe this goes into the right direction.
Many spi-mem controller drivers have a very similar debug log at the
beginning of their ->exec_op() callback implementation. This debug log is
effectively useful, so let's create one that is complete and concise
enough, so developers no longer need to write their own. The verbosity
being high, VERBOSE_DEBUG will be required in this case.
Remove the debug log from individual drivers and propose a common one.

The initial SPI controller IP from Cadence has always been implemented
into controllers from various hardware manufacturers and because of
that, it has always been (rightfully) doubled with a more specific
compatible. There are likely no reasons to keep this compatible
legitimate, alone. Make sure people do not get mislead by officially
deprecating this compatible.
While at deprecating, let's update the examples to avoid documenting
deprecated properties.

Despite being very common in commit logs, SPI NOR controllers simply do
not exist. At least, they are not as specific as the name implies. There
are SPI memory controllers which are indeed "specialized" and optimized
for handling "memories", but most of them are just generic and accept
almost any kind of opcode, address, dummy and data cycles, making them
as suitable for NANDs than NORs.
Furthermore, this controller supports any kind of bus, from single to
octal NAND, so make it clear.
Also add a comment to mention that the initial compatible naming is too
specific (but obviously kept for backward compatibility reasons).

The driver has one ordering issue and one missed case for dev_err_probe().
Address that in this mini-series.
When the allocation of the OOB buffer fails, the
qcom_spi_ecc_init_ctx_pipelined() function returns without freeing
the memory allocated for 'ecc_cfg' thus it can cause a memory leak.
Call kfree() to free 'ecc_cfg' before returning from the function
to avoid that.

The sg2044_spifmc_write() function uses 'ret' of unsigned type
size_t to capture return values from sg2044_spifmc_wait_xfer_size()
and sg2044_spifmc_wait_int(). Since these functions may return
negative error codes, using an unsigned type prevents proper
error detection, as size_t cannot represent negative values.
Change 'ret' to type int so that negative values are handled correctly.

Tracing instances have a ref count to keep them around while files within
their directories are open. This prevents them from being deleted while
they are used. The histogram code had some files that needed to take the
ref count and that was added, but the error paths did not decrement the
ref counts. This caused the instances from ever being removed if a
histogram file failed to open due to some error.

We just had a report of the assert for "btree in write buffer for
non-write buffer btree" popping during the 6.14 upgrade.
- 150TB filesystem, after a reboot the upgrade was able to continue from
where it left off, so no major damage.
But with 6.14 about to come out we want to get this tracked down asap,
and need more data if other users hit this.
Convert the BUG_ON() to an emergency read-only, and print out btree, the
key itself, and stack trace from the original write buffer update (which
did not have this check before).

The function event_{hist,hist_debug}_open() maintains the refcount of
'file->tr' and 'file' through tracing_open_file_tr(). However, it does
not roll back these counts on subsequent failure paths, resulting in a
refcount leak.
A very obvious case is that if the hist/hist_debug file belongs to a
specific instance, the refcount leak will prevent the deletion of that
instance, as it relies on the condition 'tr->ref == 1' within
__remove_instance().
Fix this by calling tracing_release_file_tr() on all failure paths in
event_{hist,hist_debug}_open() to correct the refcount.
