Subject: [PATCH 4/4] ASoC: amd: acp: fix card name length warning in SOF SoundWire machine driver
Date: Thu, 10 Sep 2026 21:46:49 +0530 [thread overview]
Message-ID: <20260910161728.1452808-5-Vijendar.Mukunda@amd.com> (raw)
In-Reply-To: <20260910161728.1452808-1-Vijendar.Mukunda@amd.com>
The ALSA snd_card driver[] field is 16 bytes (including the NUL
terminator), leaving 15 usable characters. The SOF framework
prepends a "sof-" prefix when registering the card, so
card->name = "amd-soundwire" becomes driver name "sof-amd-soundwire"
which is 17 characters and overflows the driver[16] buffer, triggering
a kernel warning.
Fix by shortening the card name to "amd-sdw"; the resulting driver
name "sof-amd-sdw" fits within the 15-character limit.
