From b4b700c5a61c6e6db976f60d4eb6ad369e838aa9 Mon Sep 17 00:00:00 2001 From: Seth Jennings Date: Wed, 13 Jun 2012 16:03:42 -0500 Subject: staging: zsmalloc: fix uninit'ed variable warning This patch fixes an uninitialized variable warning in alloc_zspage(). It also fixes the secondary issue of prev_page leaving scope on each loop iteration. The only reason this ever worked was because prev_page was occupying the same space on the stack on each iteration.
