From 0f33d8c29aadce21b02d0376547441b6f38dcede Mon Sep 17 00:00:00 2001 From: Jacob Garber Date: Mon, 22 Jul 2019 16:20:36 -0600 Subject: [PATCH] soc/qualcomm/ipq806x: Remove unnecessary allocation The bus variable doesn't live outside the scope of this function, and is only used as a convenient way for passing the pointers to all the sub-functions, so it doesn't need to be allocated. Put it on the stack instead.
