------------------------------------------------------
Subject: edac: core fix workq timer
From: Arthur Jones <ajones@xxxxxxxxxxxx>
When updating the edac_mc_poll_msec module parameter from the sysfs
/sys/module/edac_core/parameters/edac_mc_poll_msec file, we don't update
the workq timers. So that, if we move from a big poll time to a small
one, the small one won't take effect until the big one has timed out.
Here we provide a new module parameter set method to call out to the
update routine. This brings the /sys/module/edac_core/parameters
functionality up to that provided by the /sys/drivers/system/edac/mc sysfs
module parameter files so that we can remove them or at least link to the
/sys/module files...
