Subject: netlink: Avoid "cast increases required alignment of target type" on RISC.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=08c4a39ef8417de8f48874296f07ad58de46eefc;p=openvswitch

netlink: Avoid "cast increases required alignment of target type" on RISC.

This warning doesn't indicate a genuine problem, since 'nla' must be
aligned properly and NLA_ALIGN ensures that the offset is aligned properly
too.  Casting via void * suppresses the warning.
