Subject: [Patch v1 15/21] staging: gpib: Using gpib_select_device_path_ioctl

Using Linux code style for 'struct gpib_select_device_path_ioctl' to
remove typedef.

Adhering to Linux code style.

Reported by checkpatch.pl

In general, a pointer, or a struct that has elements that can reasonably be
directly accessed should never be a typedef.
