    Subject[PATCH 3.16.y-ckt 165/180] i2c: core: Export bus recovery functions
    Date
    3.16.7-ckt11 -stable review patch.  If anyone has any objections, please let me know.

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

    From: Mark Brown <broonie@kernel.org>

    commit c1c21f4e60ed4523292f1a89ff45a208bddd3849 upstream.

    Current -next fails to link an ARM allmodconfig because drivers that use
    the core recovery functions can be built as modules but those functions
    are not exported:

    ERROR: "i2c_generic_gpio_recovery" [drivers/i2c/busses/i2c-davinci.ko] undefined!
    ERROR: "i2c_generic_scl_recovery" [drivers/i2c/busses/i2c-davinci.ko] undefined!
    ERROR: "i2c_recover_bus" [drivers/i2c/busses/i2c-davinci.ko] undefined!

    Add exports to fix this.
