[PATCH v2 0/4] mailbox: mailbox-test: fix issues reported by Sashiko

[Wolfram Sang]

Changes since v1:
* added tag to patch 1 (Thanks, Geert!)
* fixed 'workqueue' typo in commit message to 'waitqueue'
* added patch 4

There were some more comments to my v1 patch series from Sashiko[1] but
I will leave it here. I don't use signals so far, so I'll leave that
part for someone else. And the rest of the comments are somehow valid
but keeping in mind that this is a debug driver only, some compromises
can be made. The patches here are worth fixing, though, IMO.

Tested with a Renesas Ironhide board (R-Car X5H).
