From 9b4eab023c0add0063260e8a5da6193fc44f1658 Mon Sep 17 00:00:00 2001 From: Adrian Schmutzler Date: Fri, 2 Oct 2020 14:23:59 +0200 Subject: [PATCH] base-files: allow exceptions when removing devicename from LEDs Without the model-based devicename for LEDs, there are still cases where a third component is required, typically when it refers to internal "devices" like phys etc. An example are the following two found on ramips: - rt2800soc-phy0::radio - rt2800pci-phy0::radio So far, the rt2800*-phy: prefixes would be removed by the devicename removal ("migration") script, and the configuration for these LEDs would be broken. To address this, this patch allows to add arguments to a call of remove_devicename_leds, which will be compared against the first part of the LED names/labels, and then be ignored by the routine, and thus not removed: remove_devicename_leds "rt2800soc-phy0" "rt2800pci-phy0" This mechanism is supposed to be used when a "devicename" applies to several devices. If only a single device is affected, it might be more effective to use a case statement and exclude the device from migration by that entirely.
