Subject: [PATCH] Detail: accept option '--brief' with '--export'
References: bsc#1095141, bsc#1100864, bsc#1112272

When called from udev with '--export' mdadm will export details about
each attached device in addition to the MD Array.
As these values are being placed in the environment of the udev process
and udev later on uses these environment values to format the uevent
message we end up overflowing the uevent buffer for larger setups.
This patch allows the option '--export' to be combined with '--brief',
which will then avoid displaying information for the attached devices
and avoid this issue.
