From e7648ffecb7fcb7400e123bb6ea989633a104fc3 Mon Sep 17 00:00:00 2001 From: Pratap Nirujogi Date: Tue, 17 Mar 2026 23:47:57 -0400 Subject: ACPI: bus: Fix MFD child automatic modprobe issue MFD child devices sharing parent's ACPI Companion fails to probe as acpi_companion_match() returns incompatible ACPI Companion handle for binding with the check for pnp.type.backlight added recently. Remove this pnp.type.backlight check in acpi_companion_match() to fix the automatic modprobe issue.
