    Subject[PATCH 3.14 005/110] extcon: max8997: Fix NULL pointer exception on missing pdata
    Date
    3.14-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Krzysztof Kozlowski <k.kozlowski@samsung.com>

    commit dfee4111febf3d9ef3a640b2cd6205c75f4e7e3d upstream.

    Fix NULL pointer exception when platform data is not supplied. The
    driver dereferenced pdata pointer where it could be NULL.
