Subject: [PATCH v2] extcon: usbc-tusb320: Set interrupt polarity based on device-tree
Date: Wed, 22 Nov 2023 09:07:48 +0100 [thread overview]
Message-ID: <20231122080749.947682-1-lukas.funke-oss@weidmueller.com> (raw)
In-Reply-To: <202311221355.yxYpTIw3-lkp@intel.com>
From: Lukas Funke <Lukas.Funke@weidmueller.com>
Remove 'IRQF_TRIGGER_FALLING' request which is not allowed on
every interrupt controller (i.e. arm64 GIC). Replace flag by a
request that depends on the actual device-tree setting.
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202311221355.yxYpTIw3-lkp@intel.com/
