Drop the same. " Also few other things to note: 1. You missed to add my Acked-by which I gave to your v2 2. This is v3 and new reviewers of this patch have absolutely no idea what got changed from v1->v2->v3. It is always good to add change log across versions 3. I asked you to add ARM64 maintainers as we would request them to pick this up via ARM64 tree. Catalin Marinas <catalin.marinas@arm.com Will Deacon <will@kernel.org> -- Regards, Sudeep

Defining `amba_dummy_clk` as static is meaningless. The amba_register_dummy_clk() function is static and is called during initialization. I think 'amba_dummy_clk' should be NULL each time when initializing Signed-off-by: Youwan Wang <youwan@nfschina.com> --- drivers/acpi/arm64/amba.c | 6 +----- 1 file changed, 1 insertion(+), 5 deletions(-)
