From: Antonio Quartulli Date: Sun, 8 May 2011 18:52:57 +0000 (+0200) Subject: batman-adv: move neigh_node->if_incoming->if_status check in find_router() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e2cbc11c0e1225bd5fe183a967fc80df3db10745;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git batman-adv: move neigh_node->if_incoming->if_status check in find_router() Every time that find_router() is invoked, if_status has to be compared with IF_ACTIVE. Moving this comparison inside find_router() will avoid to write it each time.
