Subject: rtnetlink: fix gcc -Wconversion warning
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e844463743095bc8b230f507de066d047c87476b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

rtnetlink: fix gcc -Wconversion warning

RTA_ALIGNTO is currently define as 4. It has to be 4U to prevent warning
for RTA_ALIGN and RTA_DATA expansions when -Wconversion gcc option is
enabled.
This follows NLMSG_ALIGNTO definition in <include/uapi/linux/netlink.h>.
