dmaengine: ptdma: remove PT_OFFSET to avoid redefnition
Building on ARCH=um causes a "redefined" warning, so remove this PT_OFFSET macro to avoid the warning. drivers/dma/ptdma/ptdma.h:34: warning: "PT_OFFSET" redefined 34 | #define PT_OFFSET 0x0 | In file included from ./arch/um/include/asm/thread_info.h:17, from ./include/linux/thread_info.h:60, from ./include/asm-generic/preempt.h:5, from ./arch/um/include/generated/asm/preempt.h:1, from ./include/linux/preempt.h:78, from ./include/linux/spinlock.h:55, from ./include/linux/wait.h:9, from ./include/linux/wait_bit.h:8, from ./include/linux/fs.h:6, from ./include/linux/debugfs.h:15, from drivers/dma/ptdma/ptdma-debugfs.c:12: ./arch/x86/um/shared/sysdep/ptrace_user.h:4: note: this is the location of the previous definition 4 | #define PT_OFFSET(r) ((r) * sizeof(long)) Reported-by: kernel test robot <lkp@intel.com> Fixes: 2a99524459ce ("dmaengine: ptdma: Initial driver for the AMD PTDMA") Signed-off-by: Sanjay R Mehta <sanju.mehta@amd.com> Link: https://lore.kernel.org/r/1630178908-54973-1-git-send-email-Sanju.Mehta@amd.com Signed-off-by: Vinod Koul <vkoul@kernel.org>
