Subject[PATCH 5.10 416/593] Bluetooth: Fix handling of HCI_LE_Advertising_Set_Terminated event
Date
From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

[ Upstream commit 23837a6d7a1a61818ed94a6b8af552d6cf7d32d5 ]

Error status of this event means that it has ended due reasons other
than a connection:

'If advertising has terminated as a result of the advertising duration
elapsing, the Status parameter shall be set to the error code
Advertising Timeout (0x3C).'

'If advertising has terminated because the
Max_Extended_Advertising_Events was reached, the Status parameter
shall be set to the error code Limit Reached (0x43).'

Fixes: acf0aeae431a0 ("Bluetooth: Handle ADv set terminated event")
