From 38bfab1a01c66cb1a5001dc702b0856b2f942fd5 Mon Sep 17 00:00:00 2001 From: David Woodhouse Date: Sun, 16 Dec 2007 23:26:54 -0500 Subject: [PATCH] libertas: fix buffer handling of PS_MODE commands and responses Commit 5b8845345e7385d2eb37fac22ba9ab6905988be5 (or, in case the git workflow is broken and patches get recommitted, the commit entitled 'libertas: rename and re-type bufvirtualaddr to cmdbuf' by dcbw), introduced a number of bugs where we once had a pointer to a command _payload_, but now we use the pointer to the command header instead. The fix isn't wonderfully pretty for now, but it'll get better when we finish converting all commands so the structures include the header. Signed-off-by: David Woodhouse Signed-off-by: John W.
