From 38f7d3b6530edae4c4d506d6b9dbd0ae8b8ee5e6 Mon Sep 17 00:00:00 2001 From: Patrice Chotard Date: Fri, 10 Sep 2021 16:16:20 +0200 Subject: cmd: bind: Fix driver binding on a device Fix a regression brings by commit 84f8e36f03fa ("cmd: bind: allow to bind driver with driver data") As example, the following bind command doesn't work: bind /soc/usb-otg@49000000 usb_ether As usb_ether driver has no compatible string, it can't be find by lists_bind_fdt(). In bind_by_node_path(), which called lists_bind_fdt(), the driver entry is known, pass it to lists_bind_fdt() to force the driver entry selection. For this, add a new parameter struct *driver to lists_bind_fdt(). Fix also all lists_bind_fdt() callers.
