+    diag_encl help output update
+    
+    This patch changes "scsi_enclosure" in the help output of diag_encl to
+    "sgn ..." so that it matches with the naming convention in the
+    manual page
+    
+    Before patch:
+    
+    diags/diag_encl --help
+    Usage: diags/diag_encl [-h] [-V] [...] [<scsi_enclosure>]
+    
+            [...]
+            <scsi_enclosure>: the sg device on which to operate, such
+                                as sg7; if not specified, all such
+                                devices will be diagnosed
+    man diags/man/diag_encl.8
+    ...
+    SYNOPSIS
+           diag_encl [-s [-c][-l]] [-v] [-f <path.pg2>] [sgn ...]
+           diag_encl -d
+           diag_encl --version
+           diag_encl --help
+    ...
+    
+    After patch:
+    
+    diags/diag_encl --help
+    Usage: diags/diag_encl [-h] [-V] [...] [-f <path.pg2>] [<sgn ...>]
+

+            <sgn ...>: the scsi device on which to operate, such
+                                as sg7; if not specified, all such
+                                devices will be diagnosed
+
