The buffer size is 2 Bytes and we expect to receive the same amount of
data. But sometimes we receive less data and run into uninit-was-stored
issue upon read. Hence modify the error check on the return value to match
with the buffer size as a prevention.

n_group_desc, iloc.bh, dind and gdb_bh to prevent memleak.
It's the same when ext4_handle_dirty_super() fails, but we

If there are multiple NUMA domains but the RHSA is missing in ACPI/DMAR
table, we could default to the device NUMA domain as fall back. This also
benefits the vIOMMU use case where only a single vIOMMU is exposed, hence
no RHSA will be present but device numa domain can be correct.

Currently, DRM get the capability of the mst hub only from DP_DPCD_REV and
get the slower speed even the mst hub can run in the faster speed.
As per DP-1.3, First check DP_EXTENDED_RECEIVER_CAP_FIELD_PRESENT.
If DP_EXTENDED_RECEIVER_CAP_FIELD_PRESENT is 1, read the DP_DP13_DPCD_REV to
get the fast
The relation can't be invalid here, if it is just WARN() and return 0.

You better to change the 'state' word to 'capability'.
Actually, this patch doesn't change the value of property.
It set the capability value of property.

Due to cpu hotplug, it may never be online after it's offline,
some objects in percpu pool is never free, in order to avoid
this happening, install cpu hotplug callback, call this callback
func to free objects in percpu pool when cpu going offline.
