From d6cddd3cac6650f273a2595c9f403aacee01ab05 Mon Sep 17 00:00:00 2001 From: Harvey Harrison Date: Tue, 15 Jul 2008 21:21:41 +0200 Subject: [PATCH] ide: eliminate FIT() macro Replace the FIT() macro with the kernel-provided clamp_val() macro. FIT was always being called with a member of a struct ide_timing, which are shorts, and constant constraints for the min and max. Thus we can use clamp_val, rather than clamp_t.
