From 9990552f9a26cfb07ef3edaad846543bdd013b10 Mon Sep 17 00:00:00 2001 From: Yu Watanabe Date: Thu, 4 Apr 2024 05:45:11 +0900 Subject: [PATCH] backlight: fix detection of multiple graphic cards Follow-up for e0504dd011189d97a1ea813aabfe1e696742bcf5. Hopefully, devices in PCI subsystem have some properties, thus have their udev database file. But, that may not be true. Here, we only read sysattrs of enumerated devices, hence it is not necessary to check if the device is initialized or not. --- src/backlight/backlight.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/src/backlight/backlight.c b/src/backlight/backlight.c index 61264059941..2de6c2008af 100644 --- a/src/backlight/backlight.c +++ b/src/backlight/backlight.c @@ -55,6 +55,10 @@ static int has_multiple_graphics_cards(void) { if (r < 0) return r; + r = sd_device_enumerator_allow_uninitialized(e); + if (r < 0) + return r; + r = sd_device_enumerator_add_match_subsystem(e, "pci", /* match = */ true); if (r < 0) return r; -- 2.47.3
