From a8ecbc54165fca767e75a82372a7be3810c667cf Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sat, 14 Oct 2023 22:53:11 +0200 Subject: spi: Export acpi_spi_find_controller_by_adev() Export acpi_spi_find_controller_by_adev() so that ACPI glue code which wants to dynamically create a spi_device using acpi_spi_device_alloc() or spi_new_device() on a controller, to which the code does not already have a reference, can find the controller.
