+Subject: scsi: isci: avoid array subscript warning
+
+From: Arnd Bergmann <arnd@arndb.de>
+
+commit 5cfa2a3c7342bd0b50716c8bb32ee491af43c785 upstream.
+
+I'm getting a new warning with gcc-7:
+
+isci/remote_node_context.c: In function 'sci_remote_node_context_destruct':
+isci/remote_node_context.c:69:16: error: array subscript is above array bounds [-Werror=array-bounds]
+
+This is odd, since we clearly cover all values for enum
+scis_sds_remote_node_context_states here. Anyway, checking for an array
+overflow can't harm and it makes the warning go away.
