From 638e19fc46afceb65f6bfff65b2164fbb3324cb3 Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Tue, 11 Jun 2019 22:21:09 +0900 Subject: [PATCH] ALSA: firewire-digi00x: simplify error path to begin streaming session This commit is a part of preparation to perform allocation/release of isochronous resources in pcm.hw_params/hw_free callbacks. The caller of begin_session() calls finish_session() in its error path, thus no need to call finish_session() in error path of begin_session(). This commit simplifies error path of begin_session().
