The patch titled
drivers/net/ehea/ehea_main.c: release mutex in error handling code
has been removed from the -mm tree. Its filename was
drivers-net-ehea-ehea_mainc-release-mutex-in-error-handling-code.patch
This patch was dropped because it was merged into mainline or a subsystem tree

Subject: drivers/net/ehea/ehea_main.c: release mutex in error handling code
From: Julia Lawall <julia@xxxxxxx>
The mutex is released on a successful return, so it would seem that it
should be released on an error return as well.
The semantic patch finds this problem is as follows:
(http://www.emn.fr/x-info/coccinelle/)
// <smpl>
@@
expression l;
@@
mutex_lock(l);
... when != mutex_unlock(l)
when any
when strict
(
if (...) { ... when != mutex_unlock(l)
+ mutex_unlock(l);
return ...;
}
|
mutex_unlock(l);
)
// </smpl>
