[ALSA] mpu401 - Add MPU401_INFO_UART_ONLY bitflag
Added MPU401_INFO_UART_ONLY bitflag to avoid issueing UART_ENTER command at opening streams. Some devices support only UART mode and give errors to UART_ENTER. A new module option, uart_enter, is added to snd-mpu401 driver. For UART-only devices, set uart_enter=0. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
