From 04b8290f3b95a3935ed07f2954bad9c87e8fb143 Mon Sep 17 00:00:00 2001 From: Laura Abbott Date: Mon, 8 Aug 2016 09:52:58 -0700 Subject: [PATCH] staging: android: ion: Get rid of ion_reserve ion_reserve was supposed to be used to reserve memory in board files. These days, board files are no more and there are other more controlled mechanisms for reserving memory. Get rid of this function.
