From d8af0eb6046c56e7238171ca420622541db24926 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Tue, 20 May 2008 02:17:53 +0900 Subject: libata: use ULONG_MAX to terminate reset timeout table This doesn't introduce any functional changes. This is to make reset timeout table consistent with to-be-added command timeout tables.
