> Subject: [PATCH v2 05/20] input: adxl34xx: Make adxl34x_remove() return void
>
> Up to now adxl34x_remove() returns zero unconditionally. Make it return void
> instead which makes it easier to see in the callers that there is no error to
> handle.
>
> Also the return value of i2c and spi remove callbacks is ignored anyway.
