wait_for_complete_timeout() expects a timeout in jiffies. With the
driver, some call sites converted QCA8K_ETHERNET_TIMEOUT to jiffies,
others did not. Make the code consistent by changes the #define to
include a call to msecs_to_jiffies, and remove all other calls to
msecs_to_jiffies.

So, assuming that configuration, the patch would be _decreasing_ the timeout from 50 ms to 5 ms. The change should be tested to confirm it's enough. Christian, could you do that?

That is fine, I don't really expect the remaining patches will go anywhere until next year, with net-next closing soon. Andrew
