Subject: [PATCH v2 0/3] staging: r8188eu: use completions and clean rtw_cmd_thread()

This series replaces two semaphores with three completion variables
in rtw_cmd_thread(). Completions variables are better suited for the
purposes that are explained in detail in the commit messages of patches
1/3 and 2/3. Furthermore, patch 3/3 removes a redundant 'if' statement
from that same rtw_cmd_thread().

Tested with ASUSTek Computer, Inc. Realtek 8188EUS [USB-N10 Nano]

Many thanks to Dan Carpenter <dan.carpenter@...cle.com> who helped with
his review of the RFC Patch.

v1 => v2:
	Patch 1/3: No changes;
	Patch 2/3: Replace wait_for_completion_killable() with
		   wait_for_completion() because killing the kthread is
		   not allowed and so there is no need for killable
		   wait;
	Patch 3/3: No changes.

Fabio M. De Francesco (3):
  staging: r8188eu: Use completions for signaling start and end of
    kthread
  staging: r8188eu: Use completions for signaling enqueueing
  staging: r8188eu: Remove redundant 'if' statement
