From 77867fff033ea549096c49d863c564ad7d8be36f Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Tue, 28 Jul 2009 14:44:04 -0700 Subject: [PATCH] ioat: fix type mismatch for ->dmacount ->dmacount tracks the sequence number of active descriptors. It is written to the DMACOUNT register to update the channel's view of pending descriptors in the chain. The register is 16-bits so ->dmacount should be unsigned and 16-bit as well. Also modify ->desccount to maintain alignment. This was never a problem in practice because we never compared dmacount values, but this is a bug waiting to happen.
