From bada04fcda8bd2a2bfd5519a6a7265ec9896b435 Mon Sep 17 00:00:00 2001 From: Timur Tabi Date: Thu, 15 Sep 2011 16:44:52 -0500 Subject: [PATCH] drivers/video: fsl-diu-fb: improve local variable usage in some functions Clean up the local variable usage in request_irq_local() and allocate_buf(). This streamlines the code without affecting functionality.
