-Subject: [PATCH 02/40] input: Fix .device_probe failing if SDP record is not
- found
-
-Due to changes introduced by 67a26abe53bf
-("profile: Add probe_on_discover flag") profiles may get probed when
-their profile UUID are discovered, rather than resolved, which means
-the SDP record may not be available.
-
-Fixes: https://github.com/bluez/bluez/issues/614
-
-Upstream-Status: Backport [https://github.com/bluez/bluez/commit/3a9c637010f8dc1ba3e8382abe01065761d4f5bb]
