pcrypt: use format specifier in kobject_add
[ Upstream commit b1e3874c75ab15288f573b3532e507c37e8e7656 ]
Passing string 'name' as the format specifier is potentially hazardous
because name could (although very unlikely to) have a format specifier
embedded in it causing issues when parsing the non-existent arguments
to these. Follow best practice by using the "%s" format string for
the string 'name'.
Cleans up clang warning:
crypto/pcrypt.c:397:40: warning: format string is not a string literal
(potentially insecure) [-Wformat-security]
Fixes: a3fb1e330dd2 ("pcrypt: Added sysfs interface to pcrypt")
