    Subject[PATCH 5.4 069/111] dmaengine: tegra210-adma: Fix an error handling path in tegra_adma_probe()
    Date
    From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>

    commit 3a5fd0dbd87853f8bd2ea275a5b3b41d6686e761 upstream.

    Commit b53611fb1ce9 ("dmaengine: tegra210-adma: Fix crash during probe")
    has moved some code in the probe function and reordered the error handling
    path accordingly.
    However, a goto has been missed.

    Fix it and goto the right label if 'dma_async_device_register()' fails, so
    that all resources are released.
