After commit b2b49ccb (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks depending on CONFIG_PM_RUNTIME may now be changed to depend on CONFIG_PM. Replace CONFIG_PM_RUNTIME with CONFIG_PM everywhere under drivers/iio/imu/kmx61.c Signed-off-by:

Having two or more channels with the same positive scan_index field makes no sense if the device supports buffering. Prevent this situation by failing to register such a device. Signed-off-by:

The devicetree binding for mxs-lradc defines ranges for the touchscreen properties. In order to avoid unexpected behavior like division by zero, we better check these ranges during probe and abort in error case. Additionally this patch adds an important note from the reference manual about the range of sample delay. Signed-off-by:

This patch fixes off-by-one issues in the devicetree binding of mxs-lradc. According to the i.MX23 and i.MX28 reference manuals [1][2] the range of NUM_SAMPLES is 0..31, but property ave-ctrl is substracted by 1 before used. Considering all limitations the range of DELAY is 1..2047, but also property ave-delay is substracted by 1 before used. The patch has been suggested by Hartmut Knaack and Kristina Martsenko.

This fixes parts of kmx61 error handling to make code easier to read and to be more consistent with IIO coding conventions: * prefer as single point for error handling instead of duplicating code for each function * directly return a value from a case branch instead of breaking * fix error message for writing REG_CTRL1 Also, add separate error paths for kmx61_trigger_setup/iio_triggered_buffer_setup calls.

If the DT contains an invalid channel specifier then the probe of iio_hwmon fails with the following message: iio_hwmon: probe of iio_hwmon failed with error -22 So it's better to print out the relevant channel specifier in error case to locate the problem. Signed-off-by:

Commit 4ae03019 ("staging:iio:dummy: Register same channels for device and buffer") has changed the number of parameters for iio_simple_dummy_configure_buffer() only for the IIO_SIMPLE_DUMMY_BUFFER case. Fix this by also changing the placeholder function declared in the header when buffering is not enabled. Signed-off-by:

The calculations for temperature and pressure compensation were already slightly optimized in comparison to the datasheet. So, it makes sense to optimize even a bit more, making proper use of C operators: - variable t in bmp280_compensate_temp() can be eliminated by directly returning the result of the relevant equation. - make use of the += operator and eliminate an unnecessary parenthesis level in bmp280_compensate_press(). When the initialization of the ctrl_meas register fails, the error message will now mention the right register name. During probe, i2c_set_clientdata() is called, although it is not necessary. Drop it. Signed-off-by: -
