thermal: rcar: use mutex lock instead of spin lock Current R-Car thermal driver is using spin lock for each registers read/write, but it is pointless lock. This lock is required while reading temperature, but it needs long wait (= 300ms). So, this patch used mutex lock while reading temperature, instead of spin lock for each registers.
