Subject: [PATCH 1/1] staging: ozwpan: Remove allocation from delaration line

This patch removes allocation from declaration line because
people are known to gloss over declarations.

Signed-off-by: Quentin Lambert <lambert.quentin@...il.com>

 This patch was inspired by http://www.spinics.net/lists/linux-usb/msg44389.html
 and https://lkml.org/lkml/2015/2/7/47 but I am not sure the argument is valid
 in the case of a single declaration.
