Subject: Two guids for Headset HS role?

PulseAudio currently assumes that HSP HS is identified by guid
00001108-0000-1000-8000-00805f9b34fb, but it seems[1] that the Samsung
HS6000 headset uses guid
00001131-0000-1000-8000-00805f9b34fb for the HSP profile. Does anyone
know why there are two guids for HSP HS. Should PulseAudio just assume
that the two guids mean the same thing?

I should have done a bit of research into the specification docs before
sending... It seems that the two uuids are indeed the same thing,
except that 0x1108 is used both as a service class and profile
identifier, while 0x1131 is only a service class identifier.
