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

From: Andrew Donnellan
Date: Fri Feb 10 2023 - 03:04:43 EST


From: Russell Currey <ruscur@xxxxxxxxxx>

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