Subject: [PATCH 0/3] wireless: Use complete() instead complete_all()

From: Daniel Wagner <daniel.wagner@...-carit.de>

Hi,

Using complete_all() is not wrong per se but it suggest that there
might be more than one waiter. For -rt I am reviewing all
complete_all() users and would like to leave only the real ones in the
tree. The main problem for -rt about complete_all() is that it can be
uses inside IRQ context and that can lead to unbounded amount work
inside the interrupt handler. That is a no no for -rt.

The patches grouped per subsystem and in small batches to allow
reviewing.

Patch #1 fixes a minor bug in the completion API usage. The current code
works but it could work better.

cheers,
daniel
