[PATCH] ASoC: codecs: da7210: add check for i2c_add_driver
by Jiasheng Jiang 07 Jun '22

07 Jun '22

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.

[PATCH] ASoC: cs35l45: Make bmc150_magn_remove() return void
by Uwe Kleine-König 07 Jun '22

07 Jun '22

cs35l45_remove() always returns zero. Make it return no value which makes it easier to see in the callers that there is no error to handle. Also the return value of i2c driver remove callbacks is ignored anyway. This prepares making i2c remove callbacks return void, too.
