Subject: powerpc/secvar: Use sysfs_emit() instead of sprintf()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=16943a2faf94ef671e60c7577511c0d119fbdfc8;p=linux.git

powerpc/secvar: Use sysfs_emit() instead of sprintf()

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