Subject: s390/crypto: Switch over to sysfs_emit()
X-Git-Tag: v6.13-rc1~206^2~104
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=897a42dd011079f163fe4c7267052d399a2117bc;p=thirdparty%2Fkernel%2Flinux.git

s390/crypto: Switch over to sysfs_emit()

Per Documentation/filesystems/sysfs.rst, sysfs_emit() is preferred for
presenting attributes to user space in sysfs. Convert the left-over uses
in the s390/crypto code.
