Local variables shadowing other local variables or parameters make the code needlessly hard to understand. Bugs love to hide in such code. Evidence: "[PATCH v3 1/7] migration/rdma: Fix save_page method to fail on polling error". This patch removes the local variable shadowing. Tested by adding: --extra-cflags='-Wshadow=local -Wno-error=shadow=local -Wno-error=shadow=compatible-local' To configure Signed-off-by: Alistair Francis <alistair.francis@wdc.com> --- softmmu/device_tree.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-)
