Subject: net: ipmr: drop ip_mr_init() mrt_cachep null check as we'll panic if it fails
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=af623236a9f3a20aa2f15f03cf9fe7bfd13b8889;p=openwrt%2Fstaging%2Fblogic.git

net: ipmr: drop ip_mr_init() mrt_cachep null check as we'll panic if it fails

It's not necessary to check for null as SLAB_PANIC is used and we'll
panic if the alloc fails, so just drop it.
