i2c: tiny-usb: disable zero-length read messages
commit cbdb25ccf7566eee0c2b945e35cb98baf9ed0aa6 upstream.
This driver passes the length of an i2c_msg directly to
usb_control_msg(). If the message is now a read and of length 0, it
violates the USB protocol and a warning will be printed. Enable the
I2C_AQ_NO_ZERO_LEN_READ quirk for this adapter thus forbidding 0-length
read messages altogether.
