Subject: [PATCH 10/21] libata: improve EH report formatting
Date: Mon, 16 Jul 2007 14:29:39 +0900 [thread overview]
Message-ID: <118456377939-git-send-email-htejun@gmail.com> (raw)
In-Reply-To: <11845637782629-git-send-email-htejun@gmail.com>
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.
