Subject[PATCH 5.5 076/120] ARM: at91: pm: use of_device_id array to find the proper shdwc node
Date
From: Claudiu Beznea <claudiu.beznea@microchip.com>

commit ec6e618c8c018c1361d77789a100a5f6f6317178 upstream.

Use of_device_id array to find the proper shdwc compatibile node.
SAM9X60's shdwc changes were not integrated when
commit eaedc0d379da ("ARM: at91: pm: add ULP1 support for SAM9X60")
was integrated.

Fixes: eaedc0d379da ("ARM: at91: pm: add ULP1 support for SAM9X60")
