From 61a4e9e91dd3916ef91aa4899b7271bba0248677 Mon Sep 17 00:00:00 2001 From: Timur Tabi Date: Wed, 20 Aug 2008 10:29:09 -0500 Subject: powerpc: fix memory leaks in QE library Fix two memory leaks in the Freescale QE library: add a missing kfree() in ucc_fast_init() and ucc_slow_init() if the ioremap() fails, and update ucc_fast_free() and ucc_slow_free() to call iounmap() if necessary.
