This set comprises those not dependent on patches in the 4.5 merge cycle. A second set will follow shortly with ones that are. * core in kernel interfaces - fix a possible NULL dereference that is a theoretical possibility via odd usage of iio_channel_release. Pretty much a hardening of the interface, but observed in the wild with the twl4030_charger driver. * acpi-als - report the data as processed as it is in lux. This fixes a wrong use of the IIO ABI. However, old _raw version retained to avoid breaking any userspace in the wild that is relying on that (none known but it doesn't hurt us much to retain it) * ade7753 - fix some error handling to avoid use of unitialized data. * ltr501 - use a signed return type for ltr501_match_samp_freq so as to allow returning of an error code. * mcp4725 - set name field of struct iio_dev to ensure the sysfs name attribute doesn't give NULL. * mpl115 - temperature offset sign is wrong. * stk8ba50 - IIO_TRIGGER dependency added * ti_am335x_adc - Label buffer as a software buffer. It's actually a hybrid of a true hardware buffer feeding a kfifo, but the meaning of these fields has changed a little recently and in this case it should be labeled a software buffer ensure it is allowed to use the kfifo. * vf610_adc - HAS_IOMEM dependency --- 48436e82fd2925a42293f670f3570b5c855c90c1 diff --combined drivers/iio/accel/Kconfig index edc29b173f6c,16cc5c691a55..833ea9dd4464 --- a/drivers/iio/accel/Kconfig +++ b/drivers/iio/accel/Kconfig @@@ -64,7 -64,7 +64,7 @@@ config IIO_ST_ACCEL_3AXI help Say yes here to build support for STMicroelectronics accelerometers: LSM303DLH, LSM303DLHC, LIS3DH, LSM330D, LSM330DL, LSM330DLC, - LIS331DLH, LSM303DL, LSM303DLM, LSM330. + LIS331DLH, LSM303DL, LSM303DLM, LSM330, LIS2DH12.
