Subject: [PATCH] sym53c8xx_2: Add bios_param to sym_glue.c
Date: Fri, 17 Feb 2006 15:10:43 +0100 [thread overview]
Message-ID: <43F5D963.9080009@bfh.ch> (raw)
This patch adds the scsi common function bios_param to the sym53c8xx
driver. For simplicity i just copied the code from the sym53c416 driver.
Patch applies to 2.6.16-rc3
