Subject: [PATCH] dmaengine: xilinx_dma: Remove __aligned attribute on zynqmp_dma_desc_ll
Date: Thu, 25 Oct 2018 11:05:25 -0700 [thread overview]
Message-ID: <20181025180525.28378-1-natechancellor@gmail.com> (raw)
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")
