Subject[PATCH 3/6] hid-prodikeys: Move an assignment in pk_probe()
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sat, 3 Feb 2018 17:20:01 +0100

Move one assignment for a data structure member in one local variable
so that its setting will only be performed after a corresponding memory
allocation succeeded by this function.
