thermal: gov_power_allocator: Return early in manage if trip_max is NULL
Commitda781936e7
("thermal: gov_power_allocator: Allow binding without trip points") allowed the governor to bind even when trip_max is NULL. This allows a NULL pointer dereference to happen in the manage callback. Add an early return to prevent it, since the governor is expected to not do anything in this case. Fixes:da781936e7
