From de7fe963b123365a27f82330689806226a48d088 Mon Sep 17 00:00:00 2001 From: Roger While Date: Mon, 7 Nov 2005 20:57:58 +0100 Subject: [PATCH] prism54 : Unused variable / extraneous udelay In isl_38xx.c : The variable "counter" is defined and incremented but never used except if the driver is hand-compiled setting VERBOSE > SHOW_ERROR_MESSAGES. Move the definition and the increment to within the #if VERBOSE .. block. Remove extraneous udelay's. These are not required when triggering the device.
