Dear Paolo,

please pull the following changes for 6.8.

The changes are fixes/cleanups that didn't require a fix pull and
hence landed in next.

-The uvdevice didn't return a firmware return value to
 userspace. This didn't matter since that value was unused but might
 be used in the future.

-The stfle vsie code was not 100% spec compliant because it checked
 for readability of an area that was larger than the one accessed by
 firmware. Additionally there was an issue with a mask being applied
 to early.

The following changes since commit 98b1cc82c4affc16f5598d4fa14b1858671b2263:

  Linux 6.7-rc2 (2023-11-19 15:02:14 -0800)
