Summary:                    mdev can't create character devices
Description: 
I built an embedded system and I installed it on a mini PC (CPU: GeodeGX1),
, when I load the sound driver (this driver is under development):
modprobe snd-cs5530
mdev creates a block devices instead a character devices:

ls -l /dev/snd/
brw-rw-rw-    1 root     root     116,   5 Apr  2 22:29 controlC0
brw-rw-rw-    1 root     root     116,   4 Apr  2 22:29 pcmC0D0c
brw-rw-rw-    1 root     root     116,   3 Apr  2 22:29 pcmC0D0p
brw-rw-rw-    1 root     root     116,   2 Apr  2 22:29 timer

whereas the sound devices must be created as character devices.

I believe that the problem comes from this line:
type = (path[5]=='c') ? S_IFCHR : S_IFBLK;
which must be like this:
type = (path[5]=='b') ? S_IFBLK : S_IFCHR;
