.SH "DESCRIPTION"
.PP
\fIlink\fR
is about to be reset\&. Initialize it\&. Failure from prereset makes libata abort whole reset sequence and give up that port, so prereset should be best\-effort\&. It does its best to prepare for reset sequence but if things go wrong, it should just whine, not fail\&.
