Subject: crypto: octeontx2 - Use sysfs_emit in sysfs show functions
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=37b03cb378177cd575a25da5f2a0a40c6ef639d9;p=thirdparty%2Fkernel%2Flinux.git

crypto: octeontx2 - Use sysfs_emit in sysfs show functions

Replace sprintf() with sysfs_emit() in sso_pf_func_ovrd_show() and
kvf_limits_show(). sysfs_emit() is preferred for formatting sysfs output
as it performs proper bounds checking.  No functional changes.
