From 2505aa6ce42a686b2d3db95ccdcc7bc100e7b8c0 Mon Sep 17 00:00:00 2001 From: Kevin McKinney Date: Tue, 27 Sep 2011 21:28:11 -0400 Subject: [PATCH] Staging: bcm: Alter LOC for readability/understandability purposes This patch alters a line of code to make it more readable and easier to understand. The purpose of the original line of code was to compute the amount of memory to request from kmalloc. This mulit-step algorithm was being done in one line of code, thus making it more difficult to understand. Therefore, I split this algorithm into three logical steps.
