Subject: [PATCH] spi-dw-core.c: Fix error checking for debugfs_create_dir
Date: Wed, 17 May 2023 22:31:02 +0500	[thread overview]
Message-ID: <20230517173102.14096-1-osmtendev@gmail.com> (raw)

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