[PATCH] iio: accel: bmi088: Correctly compute the address of the struct spi_device

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
