+Subject: [PATCH] tpm:openssl-tpm-engine: change variable c type from char
+ into int
+
+refer to getopt_long() function definition, its return value type is
+int. So, change variable c type from char into int.
+On arm platform, when getopt_long() calling fails, if we define c as
+char type, its value will be 255, not -1. This will cause code enter
+wrong case.
