[PATCH] brcmsmac: disable power-save related functions

[PATCH] brcmsmac: disable power-save related functions

[Arend van Spriel]

This patch fixes a regression introduced by:

  commit 6da3b6c48d79da96a36c2632053cf4f53bf48fb2
  Author: Hauke Mehrtens <hauke@hauke-m.de>
  Date:   Sun Mar 24 01:45:52 2013 +0100

      brcmsmac: remove brcms_bss_cfg->associated

The regression behaviour is described in:

http://www.spinics.net/lists/linux-wireless/msg107474.html

Before the mentioned commit the return value of
the function brcms_c_ps_allowed() was always false,
which is desired behaviour as power-save is not
supported at the moment. Therefor, the function is
changed to just return false instead of simply
reverting the mentioned commit.

Sorry, John

Hope the revised commit message has all the needed
information now. Without this patch brcmsmac is
useless for anyone using it in station mode.

The link is not a very reliable reference, it can die anytime and
there's no way to know what message it refers to. Stating the message id
would better. And the best would be to copy the full text to the commit
log, it's only few lines anyway.

Johannes gave a handy tip. Gmane has a service which uses message ids:

http://mid.gmane.org/5197DC4F.7030503@broadcom.com

If the link or service dies, one can find the email with the message id
visible from the link.

You missed my point. If gmane dies you do this:

http://lmgtfy.com/?q=5197DC4F.7030503%40broadcom.com

:D

The id above is the real message id from the email, that's why you can
use it to search from email archives, google and so on.

Would it be too hard to copy the text in the commit message? :-)

Why should somebody jump here and there just to get the description of a bug?
Imho, at least a short description should appear here. In this way also David
can immediately figure out what the problem is, without jumping on the web
(imagine many of this in one pull request) :-)


my 2 cents.
