Subject: [PATCH v3 03/24] powerpc/secvar: Use sysfs_emit() instead of sprintf()
Date: Wed, 18 Jan 2023 17:10:28 +1100 [thread overview]
Message-ID: <20230118061049.1006141-4-ajd@linux.ibm.com> (raw)
In-Reply-To: <20230118061049.1006141-1-ajd@linux.ibm.com>
From: Russell Currey <ruscur@russell.cc>
The secvar format string and object size sysfs files are both ASCII
text, and should use sysfs_emit(). No functional change.
Suggested-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
