Subject: [PATCH] EDAC/altera: Fix error checking
Date: Thu, 18 May 2023 03:15:56 +0800	[thread overview]
Message-ID: <20230517191556.367689-1-asuk4.q@gmail.com> (raw)

The function edac_debugfs_create_dir returns ERR_PTR if an error
occurs, and the appropriate way to verify for errors is to use the
inline function IS_ERR. The patch will substitute the null-comparison
with IS_ERR.
