[PATCH] debugfs: add definition of debugfs_real_fops() if CONFIG_DEBUG_FS unset

From: Jakub Kicinski
Date: Mon Nov 27 2017 - 13:51:51 EST


Recent commit moved the implementation of debugfs_real_fops()
out of the header file. The declaration, however, is only
provided if CONFIG_DEBUG_FS is set. Add an empty static inline
definition for when CONFIG_DEBUG_FS is unset.

Fixes: 7c8d469877b1 ("debugfs: add support for more elaborate ->d_fsdata")
