EDAC: Remove arbitrary limit on number of channels

2015-06-03T13:10:22+00:00

Currently set to "6", but the reset of the code will dynamically
allocate as needed.  We need to go to "8" today, but drop the check
completely to save doing this again when we need even larger numbers.

EDAC: Properly unwind on failure path in edac_init()

2015-02-23T12:13:07+00:00

edac_init() does not deallocate already allocated resources on failure
path.

Found by Linux Driver Verification project (linuxtesting.org).

 [ Boris: The unwind path functions have __exit annotation but are being
   used in an __init function, leading to section mismatches. Drop the
   section annotation and make them normal functions. ]

EDAC: Allow to pass driver-specific attribute groups

2015-02-23T12:07:41+00:00

Add edac_mc_add_mc_with_groups() for initializing the mem_ctl_info
object with the optional attribute groups.  This allows drivers to
pass additional sysfs entries without manual (and racy)
device_create_file() and co calls.

edac_mc_add_mc() is kept as is, just calling edac_mc_add_with_groups()
with NULL groups.

EDAC: Use static attribute groups for managing sysfs entries

2015-02-23T12:06:58+00:00

Instead of manual calls of device_create_file() and
device_remove_file(), use static attribute groups with proper
is_visible callbacks for managing the sysfs entries.

This simplifies the code a lot and avoids the possible races.

EDAC: Fix the leak of mci->bus->name when bus_register fails

Also use goto labels for all failure paths in
edac_create_sysfs_mci_device and update meaningless labels.

EDAC: Poll timeout cannot be zero, p2

2014-02-14T09:40:29+00:00

Sanitize code even more to accept unsigned longs only and to not allow
polling intervals below 1 second as this is unnecessary and doesn't make
much sense anyway for polling errors.
