[PATCH 1/1] edac: new fix worktodo to proper cast

[PATCH 1/1] edac: new fix worktodo to proper cast

[dougthompson]

From: Jean Delvare <khali@linux-fr.org>

The edac-core driver includes code which assumes that the work_struct
which is included in every delayed_work is the first member of that
structure. This is currently the case but might change in the future,
so use to_delayed_work() instead, which doesn't make such an
assumption.

linux-2.6.30-rc1 has the to_delayed_work() function that will allow
this patch to work
