Subject: [PATCH v2] staging: exfat: remove fs_func struct.
From: "Tetsuhiro Kohada" <Kohada.Tetsuhiro@...MitsubishiElectric.co.jp>
Remove 'fs_func struct' and change indirect calls to direct calls.
The following issues are described in exfat's TODO.
> Create helper function for exfat_set_entry_time () and
> exfat_set_entry_type () because it's sort of ugly to be calling the same functionn directly and other code calling through the fs_func struc ponters ...
The fs_func struct was used for switching the helper functions of fat16/fat32/exfat.
Now, it has lost the role of switching, just making the code less readable.
