libata: improve EH report formatting
Requiring LLDs to format multiple error description messages properly doesn't work too well. Help LLDs a bit by making ata_ehi_push_desc() insert ", " on each invocation. __ata_ehi_push_desc() is the raw version without the automatic separator. While at it, make ehi_desc interface proper functions instead of macros. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
