All files in /dev/char are symlinks (see below). Rules are comming from Gentoo.

Considering mdadm is only involved by "real" block device file, why not just
skipping symlink ?
o Udev rules used to rename /dev/sd[ab]:
#cat 65-persistent-block.rules
ENV{PHYSDEVPATH}=="/devices/pci0000:00/0000:00:1f.2/host0/target0:0:0/0:0:0:0",
NAME="raid_disk0"
ENV{PHYSDEVPATH}=="/devices/pci0000:00/0000:00:1f.2/host1/target1:0:0/1:0:0:0",
NAME="raid_disk1"
o System is Gentoo.
o Content of /dev/char:
#ls -la /dev/char/
