[PATCH][scsi-next] scsi: myrb: remove shadowed and unassigned variable ldev_num

From: Colin King
Date: Wed Feb 14 2018 - 11:23:49 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

A lower-scoped variable ldev_num is never assigned and is shadowing
the higher scoped iterator ldev_num and should be removed to avoid
using garbage ldev_num values.

Detected by CoverityScan, CID#1465226 ("Uninitialized scalar variable")

Fixes: dd47c1072226 ("scsi: myrb: Add Mylex RAID controller (block interface)")
