staging: rts5208: Use pci_device_id rather than DEFINE_PCI_DEVICE_TABLE
This patch enhances kernel style usage for the rts5208 driver.
We should prefer `struct pci_device_id` over `DEFINE_PCI_DEVICE_TABLE` to meet
kernel coding style guidelines. This issue was reported by checkpatch.

staging: dgap: implement error handling in dgap_tty_register()
- alloc_tty_driver() is deprecated so it is changed to
tty_alloc_driver()
- Pointers which are allocated by alloc_tty_driver() and kzalloc()
can be NULL so it need to check NULL for them.
- If one of those is failed, it need to add proper handler for
avoiding memory leak.
- If both of drivers are registered normally, and
then set TRUE to dgap_major_serial{print}_registered. If one
of drivers is failed to register, leave a default value as
FALSE.

staging: wlan-ng: use netdev_() instead of printk()
Replaced all uses of printk() in wlan-ng with netdev_err / _warn
where a netdev exists. If a few cases where a netdev does not yet
exist, dev_ or pr_ was used.
Checkpatch complains about lines over 80 chars or split string
constants - the messages are just too long, keeping it completely
happy would make the code less readable.

Fix potential leaks in the error paths of r8712_set_key(). In case the
algorithm specific checks fail, the function returns without enqueuing
or freeing the already allocated command and parameter structs. Use a
centralized exit path and make sure that all memory is freed correctly.
