[PATCH linux/linux-next] aic94xx: asd_read_flash: Fix uninitialized variable warning

From: Tim Gardner
Date: Wed Feb 20 2013 - 14:49:57 EST

drivers/scsi/aic94xx/aic94xx_sds.c: In function 'asd_read_flash':
drivers/scsi/aic94xx/aic94xx_sds.c:597:21: warning: 'offs' may be used uninitialized in this function [-Wmaybe-uninitialized]
drivers/scsi/aic94xx/aic94xx_sds.c:985:6: note: 'offs' was declared here

If asd_find_flash_de() fails, then 'offs' could be used without having been initialized.
Set 'offs' to zero which seems like the most reasonable value.
