Martin Schwidefsky a00bfd7147 [S390] dasd deadlock after state change pending interrupt. ... The dasd_device_from_cdev function is called from interrupt context to get the struct dasd_device associated with a ccw device. The driver_data of the ccw device points to the dasd_devmap structure which contains the pointer to the dasd_device structure. The lock that protects the dasd_devmap structure is acquire with out irqsave. To prevent the deadlock in dasd_device_from_cdev if it is called from interrupt context the dependency to the dasd_devmap structure needs to be removed. Let the driver_data of the ccw device point to the dasd_device structure directly and use the ccw device lock to protect the access.
