Hi David,

can you please apply this small one.
Thanks to David L Stevens for clarification.

mcastv6: Local variable shadows function argument

The local variable 'idev' shadows the function argument 'idev' to
ip6_mc_add_src(). Fixed by removing the local declaration, as pmc->idev
should be identical with 'idev' passed as argument.
