From 82fa8f581a954ddeec1602bed9f8b4a09d100e6e Mon Sep 17 00:00:00 2001 From: Jiasheng Jiang Date: Tue, 31 May 2022 17:47:12 +0800 Subject: [PATCH] ASoC: codecs: da7210: add check for i2c_add_driver 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.
