So use devm_kzalloc to allocate mic_dma_dev to fix it. When the Devres try to release the resources, it will call release at the following order: dma_async_device_unregister(mic_dma_dev->device); ..... kfree(mic_dma_dev) Fixes: f6206f00d8c5 ("dmaengine: mic_x100_dma: use the new helper to simplify the code") Signed-off-by: Huang Shijie <sjhuang@iluvatar.ai> Signed-off-by: Vinod Koul <vkoul@kernel.org> 2018-08-26T18:48:42Z Linus Torvalds torvalds@linux-foundation.org 2018-08-26T18:48:42Z urn:sha1:aba16dc5cf9318b4e0fe92f8261779cd9f1d2d77 Pull IDA updates from Matthew Wilcox: "A better IDA API: id = ida_alloc(ida, GFP_xxx); ida_free(ida, id); rather than the cumbersome ida_simple_get(), ida_simple_remove(). The new IDA API is similar to ida_simple_get() but better named. The internal restructuring of the IDA code removes the bitmap preallocation nonsense.

Anyway, major things here are: - new FSI driver subsystem, yet-another-powerpc low-level hardware bus - gnss, finally an in-kernel GPS subsystem to try to tame all of the crazy out-of-tree drivers that have been floating around for years, combined with some really hacky userspace implementations. This is only for GNSS receivers, but you have to start somewhere, and this is great to see. Other than that, there are new slimbus drivers, new coresight drivers, new fpga drivers, and loads of DT bindings for all of these and existing drivers.
