Subject: [PATCH v1 16/19] hid-ft260: uart: suppress unhandled report 0xb1 dmesg

Suppress the "unhandled report 0xb1" error since it's related to the UART
DCD/RI function of the multifunctional GPIO pins status, which we do not
use for serial console. The configuration of these pins is a part
of the GPIO patch set.
