Subject: [PATCH 3/8] ARM: OMAP: Don't store timers physical address
Date: Tue, 13 Nov 2012 12:13:18 -0600	[thread overview]
Message-ID: <1352830403-1706-4-git-send-email-jon-hunter@ti.com> (raw)
In-Reply-To: <1352830403-1706-1-git-send-email-jon-hunter@ti.com>

The OMAP2+ system timer code stores the physical address of the timer
but never uses it. Remove this and clean-up the code by removing the
local variable "size" and changing the names of the local variables
mem_rsrc and irq_rsrc to mem and irq, respectively.
