commit56ad91c1aaupstream. 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. Fixes:83e53a8f12("i2c: Add bus driver for for OSIF USB i2c device.")
