From 7272b8bfba35b2333b33d77f73ce75ee161880c2 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 15 Sep 2023 10:27:58 +0200 Subject: ALSA: xen: Fix -Wformat-truncation warning The compile warning with -Wformat-truncation at xen_snd_front_cfg_card() is false-positive; the loop can be only for SNDRV_PCM_DEVICES which is at most 32. For suppressing the warning, replace snprintf() with scnprintf(). As stated in the above, truncation doesn't matter.
