The IIO subsystem is redefining iio_dev->mlock to be used by the IIO core only for protecting device operating mode changes. ie. Changes between INDIO_DIRECT_MODE, INDIO_BUFFER_* modes. In this driver, mlock was being used to protect hardware state changes. In the driver, buf_lock protects both the adis16060_spi_write() and adis16060_spi_read() functions and both are always called in pair. First write, then read. Refactor the code to have one single function adis16060_spi_write_than_read() protected by the buf_lock. This removes the need for additional locking via mlock, so this locking is removed.

2017-03-21staging: bcm2835-audio: Add support for simultanous HDMI and Headphone audioMichael Zoran4-99/+450
The firmware for the Raspberry PI already supports simultanous output of audio through both the HDMI and the Headphone jack. The current implementation of ALSA doesn't expose this well to user mode since the firmware audio is represented as a single card. A newer approach is taken here and a virtual card is created for each output(HDMI, Headphones, and Traditional ALSA). The firmware has the concept of channels or streams for which the number to use is passed in the device tree. These streams are allocated to each of the virtual cards. As a side effect of this change, since each output is represented independenly it's now very easy to use PulseAudio to control the priorities of the outputs. Testing: Audacity and VLC were both loaded at the same time. Each application was assigned to a different card. With this change I was able to play different music files at the same time through the HDMI and Headphones jacks and control the audio independently.
