* Merge 4.0-rc7 into staging-nextGreg Kroah-Hartman2015-04-07
|\ | | | | | | | | | | | | We want those fixes (iio primarily) into the -next branch to help with merge and testing issues. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
| * iio: fix drivers that check buffer->scan_maskOctavian Purdila2015-03-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | If the in-kernel push interface is used we may have a different masks on the device buffer and the kernel buffer and in this case the device should generate data for the reunion of the buffers, which is available at indio_dev->active_scan_mask. Compiled tested only except for bmc150-accel which was tested at runtime with the hardware.

* | iio: improve usage of gpiod APIUwe Kleine-König2015-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions) which appeared in v3.17-rc1, the gpiod_get* functions take an additional parameter that allows to specify direction and initial value for outputs.

* iio kmx61 / PM: Replace CONFIG_PM_RUNTIME with CONFIG_PMDaniel Baluta2015-01-20
| | | | | | | | | | | | | After commit b2b49ccbdd54 (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: Daniel Baluta <daniel.baluta@intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

* iio: imu: kmx61: Enhance error handlingDaniel Baluta2015-01-05
| | | | | | | | | | | | | | | 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.
