I never got this rule. Which one is a "substantially" right? Can you give me an example? I need to understand how you'd write this to satisfy the above rule. like this: memcpy(lldev->tre_ring + lldev->tre_write_offset, &tre->tre_local[0], TRE_SIZE); or memcpy(lldev->tre_ring + lldev->tre_write_offset, &tre->tre_local[0], TRE_SIZE); or memcpy(lldev->tre_ring + lldev->tre_write_offset, &tre->tre_local[0], TRE_SIZE); or memcpy(lldev->tre_ring + lldev->tre_write_offset, &tre->tre_local[0], TRE_SIZE); -- Sinan Kaya Qualcomm Technologies, Inc. on behalf of Qualcomm Innovation Center, Inc.
