    Subject[PATCH 3.19 127/175] ARM: pxa: add regulator_has_full_constraints to corgi board file
    Date
    3.19-stable review patch.  If anyone has any objections, please let me know.

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

    From: Dmitry Eremin-Solenikov <dbaryshkov@gmail.com>

    commit 271e80176aae4e5b481f4bb92df9768c6075bbca upstream.

    Add regulator_has_full_constraints() call to corgi board file to let
    regulator core know that we do not have any additional regulators left.
    This lets it substitute unprovided regulators with dummy ones.

    This fixes the following warnings that can be seen on corgi if
    regulators are enabled:

    ads7846 spi1.0: unable to get regulator: -517
    spi spi1.0: Driver ads7846 requests probe deferral
    wm8731 0-001b: Failed to get supply 'AVDD': -517
    wm8731 0-001b: Failed to request supplies: -517
    wm8731 0-001b: ASoC: failed to probe component -517
    corgi-audio corgi-audio: ASoC: failed to instantiate card -517
