This is a note to let you know that I've just added the patch titled ASoC: codecs: da7210: add check for i2c_add_driver to the 4.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: asoc-codecs-da7210-add-check-for-i2c_add_driver.patch and it can be found in the queue-4.14 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 7a0eb551b60539473da7829fbf6e44ff8359b455 Author: Jiasheng Jiang <jiasheng@xxxxxxxxxxx> Date: Tue May 31 17:47:12 2022 +0800 ASoC: codecs: da7210: add check for i2c_add_driver [ Upstream commit 82fa8f581a954ddeec1602bed9f8b4a09d100e6e ] 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.
