Due to the previous patch it is guaranteed that the FIT msg contains
at least one request after the for-loop has finished. Use this to

Use dev_err() and dev_info() instead of pr_err() and pr_info().
Since dev_dbg() is able to report file name and line number
information, remove __FILE__ and __LINE__ from the dev_dbg() calls.
Remove the struct skd_device members and the function (skd_name())
that became superfluous due to these changes.
This patch removes the device name and serial number from log
statements. An example of the old log line format:
(skd0:STM000196603:[0000:00:09.0]): Driver state STARTING(3)=>ONLINE(4)

skd:0000:00:09.0: Driver state STARTING(3)=>ONLINE(4)

The purpose of barrier() is to prevent reordering by the compiler.
Since the compiler does not reorder calls to non-pure functions,
remove the barrier() calls from skd_reg_{read,write}{32,64}().

Currently we use nornal Linux errno values in the block layer, and while
we accept any error a few have overloaded magic meanings. This patch
instead introduces a new blk_status_t value that holds block layer specific
status codes and explicitly explains their meaning. Helpers to convert from
and to the previous special meanings are provided for now, but I suspect
we want to get rid of them in the long run - those drivers that have a
errno input (e.g. networking) usually get errnos that don't know about
the special block layer overloads, and similarly returning them to userspace
will usually return somethings that strictly speaking isn't correct
for file system operations, but that's left as an exercise for later.
For now the set of errors is a very limited set that closely corresponds
to the previous overloaded errno values, but there is some low hanging
fruite to improve it.
blk_status_t (ab)uses the sparse __bitwise annotations to allow for sparse
typechecking, so that we can easily catch places passing the wrong values.

As reported by gcc -Wmaybe-uninitialized, the cleanup path for
skd_acquire_msix tries to free the already allocated msi-x vectors
in reverse order, but the index variable may not have been
used yet:
drivers/block/skd_main.c: In function ‘skd_acquire_irq’:
drivers/block/skd_main.c:3890:8: error: ‘i’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
This changes the failure path to skip releasing the interrupts
if we have not started requesting them yet.

Simply creating a file system on an skd device, followed by mount and
fstrim will result in errors in the logs and then a BUG(). Let's remove
discard support from that driver. As far as I can tell, it hasn't
worked right since it was merged. This patch also has a side-effect of
cleaning up an unintentional shadowed declaration inside of
skd_end_request.
I tested to ensure that I can still do I/O to the device using xfstests
./check -g quick. I didn't do anything more extensive than that,
though.

Clear QUEUE_FLAG_ADD_RANDOM in all block drivers that set
QUEUE_FLAG_NONROT.
Historically, all block devices have automatically made entropy
contributions. But as previously stated in commit e2e1a148 ("block: add
sysfs knob for turning off disk entropy contributions"):
- On SSD disks, the completion times aren't as random as they
are for rotational drives. So it's questionable whether they
should contribute to the random pool in the first place.
- Calling add_disk_randomness() has a lot of overhead.
There are more reliable sources for randomness than non-rotational block
devices. From a security perspective it is better to err on the side of
caution than to allow entropy contributions from unreliable "random"
sources.
