    SubjectApplied "regulator: ltc3589: Get rid of struct ltc3589_regulator" to the regulator tree
    Date
    The patch

    regulator: ltc3589: Get rid of struct ltc3589_regulator

    has been applied to the regulator tree at

    https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git for-5.2

    All being well this means that it will be integrated into the linux-next
    tree (usually sometime in the next 24 hours) and sent to Linus during
    the next merge window (or sooner if it is a bug fix), however if
    problems are discovered then the patch may be dropped or reverted.

    You may get further e-mails resulting from automated or manual testing
    and review of the tree, please engage with people reporting problems and
    send followup patches addressing any issues that are reported if needed.

    If any updates are required or you are submitting further changes they
    should be sent as incremental updates against current git, existing
    patches will not be replaced.

    Please add any relevant lists and maintainers to the CCs when replying
    to this mail.

    Thanks,
    Mark

    Subject: [PATCH] regulator: ltc3589: Get rid of struct ltc3589_regulator

    After converting to use simplified DT parsing, the struct ltc3589_regulator
    only has a desc member. So let's remove struct ltc3589_regulator and use
    struct regulator_desc instead.
