From 7564d3b6334c5dd619827a85dd32bf7c21df6667 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 5 Nov 2019 16:18:52 +0100 Subject: [PATCH] ALSA: echoaudio: Avoid non-standard macro usage Pass the device pointer from the PCI pointer directly, instead of a non-standard macro. The macro didn't give any better readability. Also slightly refactor the code (drop the return value check from the preallocation) as it never returns an error.
