Subject: [libata] arbitrary size ATAPI PIO support bugfixes
Date: Mon, 18 Oct 2004 23:26:52 +0200 [thread overview]
Message-ID: <58cb370e04101814263985aded@mail.gmail.com> (raw)
* sg was incorrectly used instead of qc->sg in __atapi_pio_bytes()
* due to obvious typo qc->curbytes wasn't zeroed in ata_qc_new_init()
