            STM Laser: Remove Proprietary License header in vl53l0_i2c_platform.c.
            Description: vl53l0_i2c_platform.c mentions Proprietary/Confidential information. Remove this and

        commit 3355587f03c25fbdd7febd68172d3d4339762665
        Author: Kalyan Vadlamudi <kalyan-kumar.vadlamudireddy@st.com>
        Date:   Thu Dec 8 15:11:32 2016 -0800

            STM Laser: Fix compliation issue in stmvl53l0_module-cci.c.
            Description: Missing ending brace in stmvl53l0_cci_init() for the cci_client->cci_subdev check

        commit f85423250c4df248c15ffeddf35ec43d01751793
        Author: Kalyan Vadlamudi <kalyan-kumar.vadlamudireddy@st.com>
        Date:   Thu Nov 3 16:55:33 2016 -0700

            STM Laser: Fix checkpatch warnings and errors.
            Description: Use checkpatch script from 4.4 kernel and fix the errors and errors. There are still few typedef related warning in the header files

        commit 6b3796838d66acb6dbcbdf004b554468f3dc1218
        Author: Kalyan Vadlamudi <kalyan-kumar.vadlamudireddy@st.com>
        Date:   Tue Aug 16 17:50:44 2016 -0700

            STM Laser : Fix Laser initialization failure
            Description : Revert the code which powers up Laser device during module init time. CCI probe can happen after STM laser driver probe,
            which is causing issues during device initialization. Code has been modified to not power up the device during STM laser driver probe.

        commit 93b6897a2a8c6828169c2501690df7cccf8221c6
        Author: Kalyan Vadlamudi <kalyan-kumar.vadlamudireddy@st.com>

        Author: Kalyan Vadlamudi <kalyan-kumar.vadlamudireddy@st.com>
        Date:   Mon Aug 1 14:27:24 2016 -0700

            Update stmvl53l0-cci.h with new fields in cci_data

        commit 95d072e03e5724445aba17c3a055c1518be9fc7e

* Use one global buffer of MAX_I2C_XFER_SIZE byte in data space \n
* This solution is not multi-Device compliant nor multi-thread cpu safe \n
* It can be the best option for small 8/16 bit MCU without stack and limited
* ram (STM8s, 80C51 ...)
*
* @li 1 : ON_STACK/local \n
* Use local variable (on stack) buffer \n
* This solution is multi-thread with use of i2c resource lock or mutex see
* VL6180x_GetI2CAccess() \n
*
* @li 2 : User defined \n
* Per Device potentially dynamic allocated. Requires VL6180x_GetI2cBuffer()
