From 7c7fc2d44b7a660846115e65b67772b6742a14d8 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 23 Nov 2007 13:14:23 +0100 Subject: [ALSA] Fix PCM MMAP time-stamp mode When MMAP time-stamp mode is given, it's supposed to update the time-stamp only at period boundary. However, it currently updates at each status call so this is just useless. The patch fixes this misbehavior. Also it fixes the wrong check of tstamp_mode (don't use bit-and for enum).
