The indentation is weird, and you're also adding memsets of the
allocations which is a behavior change. Please take a look at the the
attached version that fixes this up.
If you really need the zeroing please send an additional patch to switch
to dma_zalloc_coherent.

Subject: aacraid: pci_alloc_consistent() failures on ARM64
There were pci_alloc_consistent() failures on ARM64 platform.
Use dma_alloc_coherent() with GFP_KERNEL flag DMA memory allocations.

[hch: tweaked indentation, removed memsets]
