From a4ed0ba9afd39b41066c4ead12a2e4e731daee4a Mon Sep 17 00:00:00 2001 From: Prarit Bhargava Date: Tue, 5 May 2015 18:36:19 -0400 Subject: [PATCH] staging: unisys: fix sig_read_data and sig_read_data functions The sig_read_data() and sig_write_data() functions are involved in 2 steps of calls. They really don't need to be and this makes for much simpler code.
