From 7c22f1aaa23370bf9ba2dd3abbccbed70dced216 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 10 Oct 2005 11:46:31 +0200 Subject: [ALSA] Remove snd_runtime_check() macro Remove snd_runtime_check() macro. This macro worsens the readability of codes. They should be either normal if() or removable asserts. Also, the assert displays stack-dump, instead of only the last caller pointer.
