2016-03-12staging: dgnc: cleanup properlySudip Mukherjee1-8/+13
dgnc_cleanup_module() was called when the module unloaded to do a total cleanup and it was also called if pci_register_driver() fails. But dgnc_cleanup_module() will try dgnc_remove_driver_sysfiles() but the sysfiles will be created only if pci_register_driver() succeeds. So if pci_register_driver() fails and we try dgnc_cleanup_module() then we were getting: [ 942.001479] BUG: unable to handle kernel NULL pointer dereference at 00000018 [ 942.001482] IP: [<c122c7a8>] sysfs_remove_file_ns+0x8/0x20 with part of the call trace as: [ 942.001544] Call Trace: [ 942.001555] [<c149acc6>] driver_remove_file+0x16/0x20 [ 942.001571] [<f864a708>] dgnc_remove_driver_sysfiles+0x18/0x40 [dgnc] [ 942.001575] [<f8643ac7>] dgnc_cleanup_module+0x47/0x260 [dgnc] [ 942.001577] [<f86cb000>] ? 0xf86cb000 [ 942.001580] [<f86cb1e6>] dgnc_init_module+0x1e6/0x1000 [dgnc] Lets have a separate cleanup function which will execute dgnc_remove_driver_sysfiles() depending on the argument passed to it.

2016-03-12staging: dgnc: unregister pci driverSudip Mukherjee1-2/+1
We may choose to load the module without the hardware present. That will register the pci driver but since probe will not succeed so dgnc_NumBoards will be 0. Now if we unload the module then the pci driver stays registered as dgnc_NumBoards is 0. And if we try to load the module again it fails with the error: "Driver 'dgnc' is already registered."

2016-03-12staging: dgnc: remove pci_unregister_driverSudip Mukherjee1-14/+5
If pci_register_driver() fails then dgnc_NumBoards can never be more than zero. dgnc_NumBoards is incremented only at the end of a successful probe. And moreover if the pci driver has failed to register then we never need to unregister it. Lets just print the warning, perform the cleanup and exit with the error code.
