In the current code, it only removes *.o and .*.o.d file when make clean, there still exists useless .*.o.cmd file, just remove it. Without this patch: [yangtiezhu@linux spi]$ make [yangtiezhu@linux spi]$ make clean [yangtiezhu@linux spi]$ ls -1 .*.o.cmd .spidev_fdx-in.o.cmd .spidev_fdx.o.cmd .spidev_test-in.o.cmd .spidev_test.o.cmd With this patch: [yangtiezhu@linux spi]$ make [yangtiezhu@linux spi]$ make clean [yangtiezhu@linux spi]$ ls -1 .*.o.cmd ls: cannot access .*.o.cmd: No such file or directory Signed-off-by: Tiezhu Yang <yangtiezhu@loongson.cn> Link: https://lore.kernel.org/r/1586230512-5507-1-git-send-email-yangtiezhu@loongson.cn Signed-off-by: Mark Brown <broonie@kernel.org>
