Subject: [PATCH] ASoC: codecs: da7210: add check for i2c_add_driver
Git-commit: 82fa8f581a954ddeec1602bed9f8b4a09d100e6e
Patch-mainline: v6.0-rc1
References: git-fixes

As i2c_add_driver could return error if fails, it should be
better to check the return value.
However, if the CONFIG_I2C and CONFIG_SPI_MASTER are both true,
the return value of i2c_add_driver will be covered by
spi_register_driver.
Therefore, it is necessary to add check and return error if fails.
