Re: [Patch v2 3/3] Bluetooth-Synchronize-SCO-eSCO-connection-requests-t.patch

[Ron Shaffer]

Certain headsets such as the Motorola H350 will reject SCO and eSCO
connection requests while the ACL is transitioning from sniff mode
to active mode. Add synchronization so that SCO and eSCO connection
requests will wait until the ACL has fully transitioned to active mode.

Hi Ron,

The commit titles of your patches are wrong. Use git format-patch and
git send-email to send your patches.
