From df7e3fdf83699328d1fdf7000ce0dc852fbb0ad9 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 25 Apr 2008 09:13:45 +0200 Subject: [ALSA] Add MPU401_INFO_NO_ACK bitflag Added MPU401_INFO_NO_ACK bitflag to ignore the ACK check for UART commands. VT172x doesn't handle ACK commands, for example.
