Subject: [PATCHv4 0/3] Reuse debug helpers for HAL client and HAL

From: Andrei Emeltchenko <[email protected]>

The patch uses hal-utils.[ch] to keep debug functions for decoding
HAL messages. They will be used in haltest and HALs.

Changes:
* v4: changed bt_uuid_t -> uint8_t * since they are both used.

Andrei Emeltchenko (3):
android: Create debug hal-utils helpers
android/debug: Convert uuid helper to use uint8_t buffer
android/hal: Add UUID debug print in socket HAL

OK I'll remove len.

I don't understand what you need the len parameter for. Won't you always
be passing 16 bytes to this function?

At this moment Android uses uint8_t * and bt_uuid_t for representing
UUID for different HALs. Convert debug helper to use uint8_t * string.
