There is a type mismatch between the buffer which is of type s16 and the samples stored, which are declared as __le16. Fix the following sparse warning: drivers/iio/imu/bmi160/bmi160_core.c:411:26: warning: incorrect type in assignment (different base types) drivers/iio/imu/bmi160/bmi160_core.c:411:26: expected signed short [signed] [short] [explicitly-signed] <noident> drivers/iio/imu/bmi160/bmi160_core.c:411:26: got restricted __le16 [addressable] [usertype] sample This is a cosmetic-type patch since it does not alter code behaviour. The le16 is going into a 16bit buf element, and is labelled as IIO_LE in the channel buffer definition. Signed-off-by:

This driver predates the availability of IIO_CHAN_INFO_SAMP_FREQ attribute wherein usage has some advantages like it can be accessed by in-kernel consumers as well as reduces the code size. Therefore, use IIO_CHAN_INFO_SAMP_FREQ to implement the sampling_frequency attribute instead of using IIO_DEVICE_ATTR() macro. Move code from the functions associated with IIO_DEVICE_ATTR() into respective read and write hooks with the mask set to IIO_CHAN_INFO_SAMP_FREQ. Signed-off-by:

Attributes that were once privately defined become standard with time and hence a special global define is used. Hence update driver ad7152 to use IIO_CHAN_INFO_SAMP_FREQ which is a global define instead of IIO_DEV_ATTR_SAMP_FREQ. Move functionality from IIO_DEV_ATTR_SAMP_FREQ attribute into IIO_CHAN_INFO_SAMP_FREQ to implement the sampling_frequency attribute. Modify ad7152_read_raw() and ad7152_write_raw() to allow reading and writing the element as well. Also add a lock in the driver's private data. Signed-off-by:

The ACCES 104-QUAD-8 is a general purpose quadrature encoder counter/interface board. The 104-QUAD-8 is capable of monitoring the outputs of eight encoders via four on-board LSI/CSI LS7266R1 24-bit dual-axis quadrature counter chips. Core functions handled by the LS7266R1, such as direction and total count, are available. Performing a write to a counter's IIO_CHAN_INFO_RAW sets the counter and also clears the counter's respective error flag. Although the counters have a 25-bit range, only the lower 24 bits may be set, either directly or via a counter's preset attribute. Interrupts are not supported by this driver. This driver adds IIO support for the ACCES 104-QUAD-8 and ACCES 104-QUAD-4. The base port addresses for the devices may be configured via the base array module parameter. Signed-off-by:

Quadrature encoders, such as rotary encoders and linear encoders, are devices which are capable of encoding the relative position and direction of motion of a shaft. This patch introduces several IIO constants for supporting quadrature encoder counter devices.

This patch adds minimal driver for the Honeywell Amplified Basic Pressure sensors series. Sensors are pretty simple but are available in many variants: - psi/mbar/kPa output, - analog/i2c/spi, - gage/differential measurement, - different measure ranges etc. Refer to datasheets for more details: http://sensing.honeywell.com/honeywell-sensing-basic-board-mount-pressure-sensors-abp-series-datasheet-323005128-c-en.pdf http://sensing.honeywell.com/index.php%3Fci_id%3D45841 Driver internals: - i2c only. measure request is done by the SMBUS QUICK cmd, so if the i2c bus doesn't support it, it is required to send a dummy byte to trigger measurement, - since iio sysfs expects kilopascals, mbar-variants are treated as their respective kPa-s, hence i2c id-table has doubled entries in one line: { "abp060mg", ABP006KG }, { "abp006kg", ABP006KG }, - psi-variants have prescaled values in config, - no temperature reads yet. Work remained: - optional temperature channel, - SPI support, - DT binding. Changes since v1: - mutex is now locked in read_raw(), - corrected error codes, - fixed coding style issues, - renamed few defines and functions abp -> abp060mg (some structs left as they were to keep the sensible meaning).

in_illuminance_scale_available_show() references the isl29018_chip->int_time variable in three places inside a for loop. The value of the int_time variable can be updated by the isl29018_set_integration_time() function, which is called by the isl29018_write_raw() function. isl29018_write_raw() locks a mutex specific to this driver when the integration time variable is updated.

The event_attrs field of iio_info structure is only initialized once whenever an object of iio_info is created. After that this field is never modified again anywhere in the kernel. So, declare event_attrs field of iio_info as a const struct attribute_group. Checked for occurences throughout the kernel using grep and coccinelle. Signed-off-by:
