Subject: [PATCH AUTOSEL 5.15 08/24] regulator: Fix error checking for debugfs_create_dir
Date: Wed, 31 May 2023 09:43:04 -0400	[thread overview]
Message-ID: <20230531134320.3384102-8-sashal@kernel.org> (raw)
In-Reply-To: <20230531134320.3384102-1-sashal@kernel.org>

From: Osama Muhammad <osmtendev@gmail.com>

[ Upstream commit 2bf1c45be3b8f3a3f898d0756c1282f09719debd ]

This patch fixes the error checking in core.c in debugfs_create_dir.
The correct way to check if an error occurred is 'IS_ERR' inline function.
