    Subject[PATCH] dmaengine: xilinx_dma: Remove __aligned attribute on zynqmp_dma_desc_ll
    Date
    Clang warns:

    drivers/dma/xilinx/zynqmp_dma.c:166:4: warning: attribute 'aligned' is
    ignored, place it after "struct" to apply attribute to type declaration
    [-Wignored-attributes]
    }; __aligned(64)
    ^
    ./include/linux/compiler_types.h:200:38: note: expanded from macro
    '__aligned'
    #define __aligned(x) __attribute__((aligned(x)))
    ^
    1 warning generated.

    As Nick pointed out in the previous version of this patch, the author
    likely intended for this struct to be 8-byte (64-bit) aligned, not
    64-byte, which is the default. Remove the hanging __aligned attribute.

    Fixes: b0cc417c1637 ("dmaengine: Add Xilinx zynqmp dma engine driver support")
