From 36f6ea2b21cce09f4f85a8fca007aa6a927804f7 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sun, 7 Jun 2015 01:52:51 +0200 Subject: [PATCH] SSB: Fix handling of ssb_pmu_get_alp_clock() Dan Carpenter reported missing brackets which resulted in reading a wrong crystalfreq value. I also noticed that the result of this function is ignored.
