From e0e7bc2cbee93778c4ad7d9a792d425ffb5af6f7 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Amadeusz=20S=C5=82awi=C5=84ski?= Date: Mon, 3 Jun 2024 12:28:18 +0200 Subject: [PATCH] ASoC: topology: Clean up route loading MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Instead of using very long macro name, assign it to shorter variable and use it instead. While doing that, we can reduce multiple if checks using this define to one.
