mei: add mei_quirk_probe function

2014-12-14T16:24:00+00:00

commit 9a123f19832702753805afe0e93db26799b91b07 upstream.

The main purpose of this function is to exclude ME devices
without support for MEI/HECI interface from binding

Currently affected systems are C600/X79 based servers
that expose PCI device even though it doesn't supported ME Interface.
MEI driver accessing such nonfunctional device can corrupt
the system.

1) We move the AMT Watchdog to use the kernel watchdog core.
the new code is still part of the MEI driver.
we didn't find any good reason to extract the the MEI driver watchdog code
from the MEI Driver to a new module.

2) Since the watchdog remains in the mei driver, exposing in-kernel
API just for AMTHI is unnecessary.

MEI new Watchdog Core Interface Patches set:

3) Code cleanup (init and probe, bug_on usage, headers and etc) was
submitted in previous patches.

drivers/staging/mei/interface.c: take size of pointed value, not pointer

2011-09-16T18:49:18+00:00

Sizeof a pointer-typed expression returns the size of the pointer, not that
of the pointed data.

The semantic patch that fixes this problem is as follows:
(http://coccinelle.lip6.fr/)

// 
@@
expression *e;
type T;
identifier f;
@@

f(...,(T)e,...,
-sizeof(e)
+sizeof(*e)
