Pass a queue_limits to blk_mq_alloc_disk and apply it if non-NULL.  This
will allow allocating queues with valid queue limits instead of setting
the values one at a time later.

Now that the driver core can properly handle constant struct bus_type,
move the memstick_bus_type variable to be a constant structure as well,
placing it into read-only memory which can not be modified at runtime.

<title>memstick: jmb38x_ms: Annotate struct jmb38x_ms with __counted_by</title>

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

As found with Coccinelle[1], add __counted_by for struct jmb38x_ms.

There are no other files referencing this function, apparently
it was left global to avoid an 'unused function' warning when
the only caller is left out. With a 'W=1' build, it causes
a 'missing prototype' warning though:

drivers/memstick/host/r592.c:47:13: error: no previous prototype for 'memstick_debug_get_tpc_name' [-Werror=missing-prototypes]

Annotate the function as 'static __maybe_unused' to avoid both
problems.

<title>memstick: fix memory leak if card device is never registered</title>

When calling dev_set_name() memory is allocated for the name for the
struct device.  Once that structure device is registered, or attempted
to be registerd, with the driver core, the driver core will handle
cleaning up that memory when the device is removed from the system.

Unfortunatly for the memstick code, there is an error path that causes
the struct device to never be registered, and so the memory allocated in
dev_set_name will be leaked.  Fix that leak by manually freeing it right
before the memory for the device is freed.

When calling dev_set_name() memory is allocated for the name for the
struct device.  Once that structure device is registered, or attempted
to be registerd, with the driver core, the driver core will handle
cleaning up that memory when the device is removed from the system.

Unfortunatly for the memstick code, there is an error path that causes
the struct device to never be registered, and so the memory allocated in
dev_set_name will be leaked.  Fix that leak by manually freeing it right
before the memory for the device is freed.

<title>memstick: r592: Fix UAF bug in r592_remove due to race condition</title>

In r592_probe, dev-&gt;detect_timer was bound with r592_detect_timer.
In r592_irq function, the timer function will be invoked by mod_timer.

If we remove the module which will call hantro_release to make cleanup,
there may be a unfinished work. The possible sequence is as follows,
which will cause a typical UAF bug.

Fix it by canceling the work before cleanup in r592_remove.

CPU0                  CPU1

                    |r592_detect_timer

  put_device;       |
  kfree(host);      |
                    |
                    | queue_work
