Subject: [PATCH] isicom: correct firmware loading
Date: Mon, 18 Sep 2006 23:02:08 +0200 (CEST) [thread overview]
Message-ID: <912929121291221@karneval.cz> (raw)
isicom: correct firmware loading
Loading of firmware didn't fail when something went wrong (returned 0). Pointer to
frame was incremented only by sizeof(frame) excluding it's data contents -- bad
idea. Tell the card we're ready just after checking is complete, not before.
