From 4674284aa74cfc6db0c54c16f9557ed8c3552409 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?N=C3=ADcolas=20F=2E=20R=2E=20A=2E=20Prado?= Date: Thu, 29 Sep 2022 16:54:53 -0400 Subject: [PATCH] ASoC: mediatek: mt8192-mt6359: Set the driver name for the card MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The ASoC core automatically populates the driver name field in the card from the card name if left unset. However, since the driver name can be at most 16 characters long, wrapping will happen if the card name is longer, which is the case for the mt8192-mt6359 driver. Explicitly set the driver name for the card in order to avoid said wrapping and have a readable driver name exposed to userspace. Signed-off-by: Nícolas F. R. A.
