Subject: [PATCH] omap_ssi_port.c: Fix error checking for debugfs_create_dir
Date: Tue, 23 May 2023 22:24:34 +0500	[thread overview]
Message-ID: <20230523172434.13477-1-osmtendev@gmail.com> (raw)

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