[ 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]
