UFSDBG_REMOVE_DEBUGFS() is not called in the driver unloading path.
So ufs debugfs directory is not removed when unloading driver. It
should be called in ufshcd_remove().
BTW, do we really need UFSDBG_ADD_DEBUGFS() and UFSDBG_REMOVE_DEBUGFS()
macros?
We can use static inline functions in ufs-debugfs.h when !CONFIG_DEBUG_FS.
#ifdef CONFIG_DEBUG_FS
void ufsdbg_add_debugfs(struct ufs_hba *hba);
void ufsdbg_remove_debugfs(struct ufs_hba *hba);
#else
static inline void ufsdbg_add_debugfs(struct ufs_hba *hba)
{
}
static inline void ufsdbg_remove_debugfs(struct ufs_hba *hba)
{
}
#endif
