bmi088_regmap_spi_write() is said to be similar to the SPI generic write function. However, regmap_spi_write() calls to_spi_device() in order to find the reference to the "struct spi_device", instead of considering that 'context' is already the correct value. This works because "struct device dev" is the first entry of "struct spi_device". Align bmi088_regmap_spi_write() and regmap_spi_write() to be more future proof, should "struct spi_device" be shuffled one day.
