Revision c0ab424238ceabcaa3a2948f283bcb94f6979c93 authored by Tejun Heo on 18 November 2005, 05:22:03 UTC, committed by Jeff Garzik on 18 November 2005, 18:11:39 UTC
sil24_error_intr logs all error interrupts. ATAPI devices generates many harmless errors which can be ignored and all serious ones are reported via sense data by SCSI layer. Don't log device errors from ATAPI devices. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
