Replace the empty modifier argument with a simple identity macro. This fixes the error reported by scripts/checkpatch.pl while keeping the original semantics unchanged. The generated code is equivalent and builds successfully. Signed-off-by: Zile Xiong <redacted> --- drivers/staging/fbtft/fbtft-bus.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-)
