Ensure that the base address used by a call to rcar_thermal_common_write() may be NULL if the SOC supports interrupts for use with the thermal device but none are defined in DT as is the case for R-Car H1 (r8a7779). Guard against this condition to prevent a NULL dereference when the device is probed. Tested on: * R-Mobile APE6 (r8a73a4) / APE6EVM * R-Car H1 (r8a7779) / Marzen * R-Car H2 (r8a7790) / Lager * R-Car M2-W (r8a7791) / Koelsch * R-Car M2-N (r8a7793) / Gose * R-Car D3 ES1.0 (r8a77995) / Draak Fixes: 1969d9dc ("thermal: rcar_thermal: add r8a77995 support") Signed-off-by:
