Description

Gendisk ldv_1_block_gendisk which is passed as first parameter to block_device_operations->release is not properly initialized.
It should have the same value as 

ldv_1_disk_gendisk = data->arg1;

passed to block_device_operations->open.

See ldv_block_scenario_1 function
and call 

    ldv_block_scenario_release_1_2(ldv_1_ops_block_device_operations->release, ldv_1_block_gendisk,
                                   ldv_1_ldv_param_2_1_default);

EMG generated two variables according to block device operations specification for gendisk. I have fixed the specification and EMG now get gendisk within a registration signal and passes it to release callback.

Implemented and available in master since f6e6ad09.
