From d948035a928400ae127c873fbf771389bee18949 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 8 Jan 2008 18:05:26 +0100 Subject: [ALSA] Remove PCM xfer_align sw params The xfer_align sw_params parameter has never been used in a sane manner, and no one understands what this does exactly. The current implementation looks also buggy because it allows write of shorter size than xfer_align. So, if you do partial writes, the write isn't actually aligned at all. Removing this parameter will make some pcm_lib_* code more readable (and less buggy).
