Get rid of the mdesc pointer in the fixup function call. No one uses the mdesc pointer, it shouldn't be modified anyway, and we can't wrap it, so let's remove it. Platform files found by: $ regexp=$(git grep -h '\.fixup.*=' arch/arm | sed 's!.*= *\([^,]*\),* *!\1!' | sort -u | tr '\n' '|' | sed 's,|$,,;s,|,\\|,g') $ git grep $regexp arch/arm Acked-by: Nicolas Pitre <nicolas.pitre@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
