Subject: [PATCH 1/3] wl1251: fix TSF calculation
Date: Sat, 16 Jun 2012 22:26:46 +0300	[thread overview]
Message-ID: <1339874808-9991-2-git-send-email-notasas@gmail.com> (raw)
In-Reply-To: <1339874808-9991-1-git-send-email-notasas@gmail.com>

Cast MSB part of current TSF to u64 to prevent loss of most
significant bits. MSB should also be shifted by 32.

Patch based on old maemo patch by:
Yuri Kululin <ext-yuri.kululin@nokia.com>
Yuri Ershov <ext-yuri.ershov@nokia.com>
