From abacc904c73b056bbc4b6e3c98ea86dc57a9981b Mon Sep 17 00:00:00 2001 From: Roy Vegard Ovesen Date: Mon, 20 Oct 2025 22:15:08 +0200 Subject: [PATCH] ALSA: usb-audio: don't log messages meant for 1810c when initializing 1824c [ Upstream commit 75cdae446ddffe0a6a991bbb146dee51d9d4c865 ] The log messages for the PreSonus STUDIO 1810c about device_setup are not applicable to the 1824c, and should not be logged when 1824c initializes. Refactor from if statement to switch statement as there might be more STUDIO series devices added later.
