[ Upstream commit 64057f051f20c2a2184b9db7f8037d928d68a4f4 ]
Serdev recv_buf() callback is supposed to return the amount of bytes
consumed, therefore an int in between 0 and count.
Do not return negative number in case of issue, just print an error and
return count. This fixes a WARN in ttyport_receive_buf().

Bluetooth: mediatek: fix up an error path to restore bdev->tx_state2019-05-08T05:21:52+00:00Sean Wangsean.wang@mediatek.com2019-02-14T23:19:35+00:00urn:sha1:8897bf03ec303e64d8cb3e609e2aa90e5dc9275d
commit 77f328dbc6cf42f22c691a164958a5452142a542 upstream.
Restore bdev->tx_state with clearing bit BTMTKUART_TX_WAIT_VND_EVT
when there is an error on waiting for the corresponding event.

In case memory resources for *fw* were allocated, release them before
return.

We're supposed to pass the number of elements in the mtk_recv_pkts, not
the number of bytes.

This adds a driver based on serdev driver for the MediaTek serial protocol
based on running H:4, which can enable the built-in Bluetooth device inside
MT7622 SoC.
