Message-Id: <1452345621-15908-12-git-send-email-a@unstable.cc> Date: Sat, 9 Jan 2016 21:20:16 +0800 From: Antonio Quartulli <a@...table.cc> To: davem@...emloft.net Cc: netdev@...r.kernel.org, b.a.t.m.a.n@...ts.open-mesh.org, Markus Elfring <elfring@...rs.sourceforge.net>, Marek Lindner <mareklindner@...mailbox.ch>, Antonio Quartulli <a@...table.cc> Subject: [PATCH 11/16] batman-adv: Split a condition check From: Markus Elfring <elfring@...rs.sourceforge.net> Let us split a check for a condition at the beginning of the batadv_is_ap_isolated() function so that a direct return can be performed in this function if the variable "vlan" contained a null pointer.
