Bug#379352: mdadm: checkarray --all gives error on mixed RAID system.

[Paul Brook]

Package: mdadm
Version: 2.5.2-7
Severity: normal
Tags: patch


checkarray --all gives the following error on a system with both RAID1
and RAID0 arrays:

checkarray: E: /sys/block/md4/md/sync_action not writeable.

Patch below fixes this by making --all only select devices that have
md/sync_action.
