[ALSA] Change an arugment of snd_mpu401_uart_new() to bit flags
Change the 5th argument of snd_mpu401_uart_new() to bit flags instead of a boolean. The argument takes bits that consist of MPU401_INFO_XXX flags. The callers that used the value 1 there are replaced with MPU401_INFO_INTEGRATED. Signed-off-by: Takashi Iwai <tiwai@suse.de>
