debugfs: Fix !DEBUG_FS debugfs_create_automount
If DEBUG_FS=n, compile fails with the following error:
kernel/trace/trace.c: In function 'tracing_init_dentry':
kernel/trace/trace.c:8658:9: error: passing argument 3 of 'debugfs_create_automount' from incompatible pointer type [-Werror=incompatible-pointer-types]
8658 | trace_automount, NULL);
| ^~~~~~~~~~~~~~~
| |
| struct vfsmount * (*)(struct dentry *, void *)
In file included from kernel/trace/trace.c:24:
./include/linux/debugfs.h:206:25: note: expected 'struct vfsmount * (*)(void *)' but argument is of type 'struct vfsmount * (*)(struct dentry *, void *)'
206 | struct vfsmount *(*f)(void *),
