'channels' is allocated via kmemdup and it is never freed in the subsequent error paths. Use 'indio_dev->channels' directly instead, so that we avoid such memory leak problem. Signed-off-by:

Currently, proximity sensor boundary check is done inside the switch block but outside the case statement.Since this code will never get executed, moved the check outside the switch case statement. 867 case IIO_PROXIMITY: 868 switch (dir) { // Following line has been moved outside the switch block. 869 if (val > LTR501_PS_THRESH_MASK) 870 return -EINVAL; 871 case IIO_EV_DIR_RISING: Signed-off-by:Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppuswamy@linux.intel.com> Signed-off-by:

This is mostly part of an effort to clean out our current warnings and make the autobuilder build reports more useful. Still a worthwhile if trivial cleanup! Signed-off-by:

Add optional DT properties to set open delay, sample delay and number of averages per sample for each adc step. Open delay, sample delay and averaging are some of the parameters that affect the sampling rate and accuracy of the sample. Making these parameters configurable via DT will help in balancing speed vs accuracy. Signed-off-by:

This driver adds the initial support for the ACPI Ambient Light Sensor as defined in Section 9.2 of the ACPI specification (Revision 5.0) [1]. Sensors complying with the standard are exposed as ACPI devices with ACPI0008 as hardware ID and provide standard methods by which the OS can query properties of the ambient light environment the system is currently operating in. This driver currently allows only to get the current ambient light illuminance reading through the _ALI method, but is ready to be extended extended to handle _ALC, _ALT and _ALP as well.

Export the oversampling ratio so that the user can change the number of repetions for x/y/z axis. The sampling frequency is limited by the oversampling ratio. The available sampling frequencies might change depending on the values of oversampling_ratio.

Some magnetometers can perform a number of repetitions in HW for each measurement to increase accuracy. One example is Bosch BMC150: http://ae-bst.resource.bosch.com/media/products/dokumente/bmc150/BST-BMC150-DS000-04.pdf. Introduce an interface to set the oversampling ratio for these devices.

The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer functionality only, can still be compiled if GPIOLIB is not enabled. Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where appropriate. Signed-off-by:

Merge tag 'iio-for-v4.2a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: First round of new drivers, functionality and cleanups for the 4.2 cycle New drivers / device support * st sensors driver, lsm303dlh magnetometer support. * ltr501 - support ltr301 and ltr559 chips. New functionality * IIO_CHAN_INFO_CALIBEMISSIVITY for thermopile sensors. * kxcjk1013 - make driver operational with external trigger. * Add iio targets to the tools Makefile. Cleanups * st sensors - more helpful error message if device id wrong or irq request fails, explicitly make the Block Data Update optional rather than relying on writes to address 0 not doing anything, make interrupt support optional (Not always wired, and not all devices actually have an interrupt line.) * kxcjk-1013 white space additions for readability, add the KXCJ9000 ACPI id as seen in the wild. * sx9500 - GPIO reset support, refactor the GPIO interrupt code, add power management, optimize power usage by powering down when possible, rename the gpio interrupt pin to be more useful, trivial return path simplification, trivial formatting fixes. * isl29018 - move towards ABI compliance with a view to moving this driver out of staging, add some brackets to ensure code works as expected. Note there is no actual bug as the condition being tested is always true (with current devices). * ltr501 - add regmap support to get caching etc for later patches, fix a parameter sanity check that always fails (bug introduced earlier in this series), ACPI enumeration support, interrupt rate control support, interrupt support in general and integration time control support, code alignment cleanups. * mma9553 - a number of little cleanups following a review from Hartmut after I'd already applied the original driver patch. * tmp006 - prefix some defines with TMP006 for consistency. * tsl4531 - cleanup some wrong prefixes, presumably from copy and paste. * mlx90614 - check for errors in read values, add power management, add emissivity setting, add device tree binding documentation, fix a duplicate const warning. * ti_am335x_adc - refactor the DT parsing into a separate function.
