Subject: [SCSI] dc395x: uninitialized variable in device_alloc()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=208afec4f3be8c51ad6eebe6611dd6d2ad2fa298;p=linux-beck.git

[SCSI] dc395x: uninitialized variable in device_alloc()

This bug was introduced back in bitkeeper days in 2003.  We use
"dcb->dev_mode" before it has been initialized.
