This patch adds a channel type check at the beginning of the ad2s90_read_raw function. Since ad2s90 has only one channel, it just checks if the given channel is the expected one and if not, return -EINVAL. Signed-off-by:

Previously, devm_iio_device_register was being called before the spi_setup call and the spi_device's max_speed_hz and mode assignments. This could lead to a race condition since the driver was still being set up after it was already made ready to use. To fix it, this patch moves the device registration to the end of ad2s90_probe.

This patch removes an initial assignment to the variable ret at probe, that was always overwritten. Signed-off-by:

Matheus Tavares authored
Previously, ad2s90_probe ignored the return code from spi_setup, not handling its possible failure. This patch makes ad2s90_probe check if the code is an error code and, if so, do the following: - Call dev_err with an appropriate error message. - Return the spi_setup's error code. Note: The 'return ret' statement could be out of the 'if' block, but this whole block will be moved up in the function in the patch: 'staging:iio:ad2s90: Move device registration to the end of probe'.

Previously, when spi_read returned an error code inside ad2s90_read_raw, the code was ignored and IIO_VAL_INT was returned. This patch makes the function return the error code returned by spi_read when it fails. Signed-off-by:

Add device tree table for matching vendor ID. Note that as the driver is still heavily in flux and there are some non obvious aspects to a comprehensive binding, that binding will be submitted at a later date (before leaving staging!) Signed-off-by:

LIS3MDL and LSM9DS1 are missing BDU settings in their register maps, so add them. I don't have a LIS3MDL sensor to test, but this works correctly on the LSM9DS1, which has the same register map. Signed-off-by:

Update the sensor settings to support the LSM9DS1 sensor. Although the LSM9DS1 accelerometer and gyroscope are coupled together to use the same FIFO, the magnetometer is separate and can be cleanly supported without refactoring the existing driver. Signed-off-by:

Rather than adding breaks, add return -EINVAL to the specific case statements to clarify the error return paths. Fix also saves 50 bytes.

In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. Notice that in this particular case, I replaced "...and fall through." with the specific string "fall through", which is what GCC is expecting to find thus supressing this false positive. As Peter has observed this breaks the nice English flow, which is less than ideal, but short of teaching GCC to read English, there isn't a lot that we can do about it.

The charme of devm_* functions is that you don't need to care about them in the error path. In this case it is valid to just return NULL which makes the device fail to probe and then the two gpios and the allocated memory are freed automatically by the driver core. Signed-off-by:
