Subject: staging: vt6656: 64bit fixes: vCommandTimerWait change calculation of
timer.
From: Malcolm Priestley <[email protected]>
commit 70e227790d4ee4590023d8041a3485f8053593fc upstream.
The timer appears to run too fast/race on 64 bit systems.
Using msecs_to_jiffies seems to cause a deadlock on 64 bit.
A calculation of (MSecond * HZ) / 1000 appears to run satisfactory.
Change BSSIDInfoCount to u32.
After this patch the driver can be successfully connect on little endian 64/32
bit systems.
