Subject: [PATCH v2 0/3] Bluetooth: fix recv_buf() return value

From: Francesco Dolcini <francesco.dolcini@...adex.com>

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().

In addition to that a small cleanup patch is added on btnxpuart to remove a useless assignment.

v2:
 - improved commit messages

Francesco Dolcini (3):
  Bluetooth: btnxpuart: fix recv_buf() return value
  Bluetooth: btmtkuart: fix recv_buf() return value
  Bluetooth: btnxpuart: remove useless assignment
