Bluetooth: Add new quirk for broken read key length on ATS2851
[ Upstream commit 48201a3b3f398be6a01f78a14b18bd5d31c47458 ] The ATS2851 controller erroneously reports support for the "Read Encryption Key Length" HCI command. This makes it unable to connect to any devices, since this command is issued by the kernel during the connection process in response to an "Encryption Change" HCI event. Add a new quirk (HCI_QUIRK_BROKEN_ENC_KEY_SIZE) to hint that the command is unsupported, preventing it from interrupting the connection process. This is the error log from btmon before this patch: > HCI Event: Encryption Change (0x08) plen 4 Status: Success (0x00) Handle: 2048 Address: ... Encryption: Enabled with E0 (0x01) < HCI Command: Read Encryption Key Size (0x05|0x0008) plen 2 Handle: 2048 Address: ... > HCI Event: Command Status (0x0f) plen 4 Read Encryption Key Size (0x05|0x0008) ncmd 1 Status: Unknown HCI Command (0x01) Signed-off-by: Vinicius Peixoto <nukelet64@gmail.com> Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
