We want the IIO and staging driver fixes in here as well. Signed-off-by: Greg Kroah-Hartman

iio: st_pressure: st_accel: pass correct platform data to init

2018-03-10T16:28:05+00:00

Commit 7383d44b added a pointer pdata which get set to the default platform_data when non was defined in the device. But it did not pass this pointer to the st_sensors_init_sensor call but still used the maybe uninitialized platform_data from dev. This breaks initialization when no platform_data is given and the optional st,drdy-int-pin devicetree option is not set. This commit fixes this.

Revert "iio: accel: st_accel: remove redundant pointer pdata"

2018-03-10T16:21:32+00:00

This reverts commit 585ed27d06151f98e39238298f43ee261314ae74. This removed code which was unused due to a bug in commit 7383d44b. To fix this bug the code is needed. Thus this revert. Signed-off-by: Michael Nosthoff Signed-off-by: Jonathan Cameron

iio: Replace occurrences of magic number 0 by IIO_CHAN_INFO_RAW

2018-03-07T20:14:36+00:00

Usually, functions responsible for reading raw data typically relies on values from iio_chan_info_enum to correctly identify the type of data to be read. There is a set of a device driver that uses the magic number 0 instead of IIO_CHAN_INFO_RAW. This patch improves the readability by replaces the magic number 0 for the appropriate IIO_CHAN_INFO_RAW in six devices driver in the IIO subsystem.

iio: accel: bmc150: Remove redundant func in dev_dbg()

2018-02-24T13:29:36+00:00

Dynamic debug has a run time knob to enable function name printing. Remove this from dev_dbg() calls. Furthermore, functional tracing when enabled can show what function is called, therefore remove empty dev_dbg() calls. Signed-off-by: Andy Shevchenko Signed-off-by: Jonathan Cameron

iio: accel: use strlcpy() instead of strncpy()

gcc-8 reports drivers/iio/accel/st_accel_i2c.c: In function 'st_accel_i2c_probe': ./include/linux/string.h:245:9: warning: '__builtin_strncpy' specified bound 20 equals destination size [-Wstringop-truncation] The compiler require that the length of the dest string is greater than the length we want to copy to make sure the dest string is nul-terminated. We can just use strlcpy() to avoid this warning. Signed-off-by: Xiongfeng Wang Signed-off-by: Jonathan Cameron

iio: mma8452: replace license description with SPDX specifier

This replaces the custom license information text with the appropriate SPDX identifier. While the information here stays the same, it is easier to read.

iio: accel: bmc150: Add OF device ID table

2017-12-02T11:59:33+00:00

The driver doesn't have a struct of_device_id table but supported devices are registered via Device Trees. This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF. The I2C device ID table entries have the .driver_data field set, but they are not used in the driver so weren't set in the OF device table entries.

iio: accel: st_accel: remove redundant pointer pdata
