From 53945f5b8ae550d8c6f7ac8ed9b1e496778fad45 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 10 May 2017 20:30:34 +0200 Subject: [PATCH] ALSA: rme96: Convert to the new PCM ops Replace the copy and the silence ops with the new PCM ops. The conversion is straightforward with standard helper functions, and now we can drop the bytes <-> frames conversions in callbacks.
