ok, sorry for that :)

recently we are now allowing to register debugfs for syscon regmap, then 
i hit a lot of:
(NULL device *): Failed to create debugfs directory

so i sent this patch to fix that by using the of_node name to create 
debugfs.

but later i found we have:
commit a430ab205d29e7d1537b220fcf989b8080d8267f
Author: Fabio Estevam <fabio.estevam@xxxxxxx>

    regmap: debugfs: Disambiguate dummy debugfs file name

which would fix that in another way by naming dummy0, dummy1, dummy2.

even if the issue is fixed, i wonder could we still have this patch to 
make it more readable:

+++ b/drivers/mfd/syscon.c
@@ -109,6 +109,7 @@ static struct syscon *of_syscon_register(struct 
device_node *np)
        syscon_config.reg_stride = reg_io_width;
        syscon_config.val_bits = reg_io_width * 8;
        syscon_config.max_register = resource_size(&res) - reg_io_width;
+       syscon_config.name = of_node_full_name(np);




and i've sent 2 more patches to fix the memleak there:
https://patchwork.kernel.org/patch/10261409
https://patchwork.kernel.org/patch/10261411

and sorry again, i forgot to add a cover letter, and i should CC you the 
whole series.
