Subject: [PATCH 05/63] ide-cd: add missing 'ireason' masking to cdrom_write_intr()
Date: Thu, 20 Dec 2007 01:55:17 +0100 [thread overview]
Message-ID: <200712200155.17499.bzolnier@gmail.com> (raw)
Mask 'ireason' variable with 0x3 so the valid interrupt reason value
is passed to cdrom_write_check_ireason() for checking.
