[PATCH] sil24: make error_intr less verbose
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>
