From 8a60958923e6cea34de024eb7e494de0bee3c7f2 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Mon, 27 Sep 2021 15:59:44 +0200 Subject: [PATCH] ABI: sysfs-class-bdi: use What: to describe each property Instead of listing all bdi entries inside the description, add one entry for each, just like the remaining ABI files. That allows get_abi.pl script to properly parse it.
