From d2f4d47d84f8c665ab9babb2cc84d2e7872a96e1 Mon Sep 17 00:00:00 2001 From: Ido Yariv Date: Thu, 31 Mar 2011 10:07:00 +0200 Subject: wl12xx: Simplify TX blocks accounting The total number of TX memory blocks may change when the dynamic memory option is enabled. The current implementation only tracks the available memory blocks, which over-complicates TX blocks accounting. By tracking the number of allocated blocks, calculation of the number of available blocks becomes simpler and cleaner. It simply equals the total number of TX memory blocks minus the allocated ones. Also, remove some unnecessary castings and use union member accesses instead.
