Subject: [PATCH v6 06/26] powerpc/secvar: Use sysfs_emit() instead of sprintf()

From: Andrew Donnellan <[email-masked]>
Date: Fri, 10 Feb 2023 19:03:41 +1100

From: Russell Currey <[email-masked]>

The secvar format string and object size sysfs files are both ASCII
text, and should use sysfs_emit().  No functional change.
