2017-01-23iio: accel: fix Kconfig warningLinus Walleij
commit 762227721fe6225be5b6d233ef681aea5871f5f3 "iio: accel: st_accel: handle deprecated bindings" attempted to be smart and let users use the old I2C driver and the new SPI driver, or the old SPI driver and the new I2C driver in combination for the LIS3LV02, and put the restrictions on the I2C and SPI subdrivers not not be combined with the old subdrivers. This doesn't work since the IIO ST accel top-level component selects the I2C and SPI subdrivers, resulting in the following Kconfig noise: warning: (IIO_ST_ACCEL_3AXIS) selects IIO_ST_ACCEL_I2C_3AXIS which has unmet direct dependencies (IIO && !SENSORS_LIS3_I2C && IIO_ST_ACCEL_3AXIS && IIO_ST_SENSORS_I2C) warning: (IIO_ST_ACCEL_3AXIS) selects IIO_ST_ACCEL_SPI_3AXIS which has unmet direct dependencies (IIO && !SENSORS_LIS3_SPI && IIO_ST_ACCEL_3AXIS && IIO_ST_SENSORS_SPI) (...) This fixes the issue by putting the dependencies directly in the top-level component instead, so that it never gets to select its unselectable subcomponent.

2017-01-22iio: trigger: free trigger resource correctlyAlison Schofield
These stand-alone trigger drivers were using iio_trigger_put() where they should have been using iio_trigger_free(). The iio_trigger_put() adds a module_put which is bad since they never did a module_get. In the sysfs driver, module_get/put's are used as triggers are added & removed. This extra module_put() occurs on an error path in the probe routine (probably rare). In the bfin-timer & interrupt trigger drivers, the module resources are not explicitly managed, so it's doing a put on something that was never get'd. It occurs on the probe error path and on the remove path (not so rare). Tested with the sysfs trigger driver. The bfin & interrupt drivers were build tested & inspected only.

2017-01-22iio: trigger: close race condition in acquiring trigger referenceAlison Schofield
In iio_trigger_write_current() we find the trigger we want while holding mutex on the list of triggers, but we don't actually do a get on it while holding mutex. We wait until further validations are completed and we're sure it's the one we want. Race condition is that it could be freed by the time we do the get. Solution is to grab the trigger (iio_trigger_get) as soon as we find it while holding mutex on the list of triggers. If later we decide it's not the right one, put it back. (iio_trigger_put).

2017-01-22staging: iio: isl29028: add runtime power management supportBrian Masney
This patch adds runtime power management support to the isl29028 driver. It defaults to powering off the device after two seconds of inactivity. isl29028_chip_init_and_power_on() currently only zeros the CONFIGURE register on the chip, which will cause the chip to turn off. This patch also renames that function to isl29028_clear_configure_reg() since it is now used in several places.

This patch moves the isl29028_set_als_scale() call from isl29028_chip_init_and_power_on() to isl29028_set_als_ir_mode().

2017-01-21iio: bmi160: use variable names for sizeof() operatorAlison Schofield
Replace the types with the actual variable names when using the sizeof() operator. This is kernel preferred style as it's more obvious that it is correct. Signed-off-by: Alison Schofield <amsfield22@gmail.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2017-01-21iio: light: cm3605: mark PM functions as __maybe_unusedArnd Bergmann
When CONFIG_PM_SLEEP is disabled, we get a harmless warning drivers/iio/light/cm3605.c:292:12: error: 'cm3605_pm_resume' defined but not used [-Werror=unused-function] drivers/iio/light/cm3605.c:281:12: error: 'cm3605_pm_suspend' defined but not used [-Werror=unused-function] Marking the functions as possibly unused avoids the warning without needing to add an #ifdef.

2017-01-21iio: pressure: ms5611: claim direct mode during oversampling changesAlison Schofield
Driver was checking for direct mode before changing oversampling ratios, but was not locking it. Use the claim/release helper functions to guarantee the device stays in direct mode while the oversampling ratios are being updated. Continue to use the drivers private state lock to protect against conflicting direct mode access of the state data.

Driver was checking for direct mode but not locking it. Use the claim/release helper functions to guarantee the device stays in direct mode during raw reads of proximity data.
