Subject: softmmu/device_tree: Fixup local variables shadowing
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5567fa825ab9bdc4688308bea7816e2f969b65c3;p=qemu.git

softmmu/device_tree: Fixup local variables shadowing

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
