This is an identical change to the wireless/lib80211 of the same name. In preparing to remove all stack VLA usage from the kernel[1], this removes the discouraged use of AHASH_REQUEST_ON_STACK in favor of the smaller SHASH_DESC_ON_STACK by converting from ahash-wrapped-shash to direct shash. By removing a layer of indirection this both improves performance and reduces stack usage. The stack allocation will be made a fixed size in a later patch to the crypto subsystem.

2018-07-28iio: chemical: Add support for Bosch BME680 sensorHimanshu Jha6-0/+1291
Bosch BME680 is a 4-in-1 sensor with temperature, pressure, humidity and gas sensing capability. It supports both I2C and SPI communication protocol for effective data communication. The device supports two modes: 1. Sleep mode 2. Forced mode The measurements only takes place when forced mode is triggered and a single TPHG cycle is performed by the sensor. The sensor automatically goes to sleep after afterwards. The device has various calibration constants/parameters programmed into devices' non-volatile memory(NVM) during production and can't be altered by the user. These constants are used in the compensation functions to get the required compensated readings along with the raw data. The compensation functions/algorithms are provided by Bosch Sensortec GmbH via their API[1]. As these don't change during the measurement cycle, therefore we read and store them at the probe. The default configs supplied by Bosch are also set at probe. 0-day tested with build success.
