Subject: [PATCH] ALSA: hda: add CSC3551 support for UM5302TA

From: He Wang <xw897002528@...il.com>

ASUS UM5302TA are using csc3551, or cs35l41, which is connected to the
laptop by I2C bus. This patch adds quirk for the sound card, and avoid
ACPI DSD things for i2c-multi-instantiate cases like CLSA0100.

Patch is made by XiaoYan Li. It is tested by us on ASUS UM5302TA.
