[PATCH 4.9 45/51] xfs: fix xfs_mode_to_ftype() prototype

[Greg Kroah-Hartman]

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------


From: Arnd Bergmann <arnd@xxxxxxxx>

commit fd29f7af75b7adf250beccffa63746c6a88e2b74 upstream.

A harmless warning just got introduced:

fs/xfs/libxfs/xfs_dir2.h:40:8: error: type qualifiers ignored on function return type [-Werror=ignored-qualifiers]

Removing the 'const' modifier avoids the warning and has no
other effect.

Fixes: 1fc4d33fed12 ("xfs: replace xfs_mode_to_ftype table with switch statement")
