From 78bd8f5126f854872cc109cbac21c675d8539f3f Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 15 Sep 2023 10:27:52 +0200 Subject: ALSA: usb-audio: scarlett_gen2: Fix -Wformat-truncation warning The recent enablement of -Wformat-truncation leads to a false-positive warning for mixer_scarlett_gen2.c. For suppressing the warning, replace snprintf() with scnprintf(). As stated in the above, truncation doesn't matter.
