Subject: [PATCH 2.6.20-rc3] fix broken retval test in sr_block_ioctl
Date: Tue, 2 Jan 2007 17:24:39 -0500	[thread overview]
Message-ID: <200701021724.39613.liml@rtr.ca> (raw)

With recent kernels (and possibly much older ones, too),
ioctl() calls for ATAPI devices never make it to the driver layers.

The reason for this is a borked return code test in drivers/scsi/sr.c.
This patch fixes it.
