Gcc issued the warning when compiling CryptoPkg:
CryptoPkg/Library/Include/CrtLibSupport.h:135:17: warning: type of 'memset' does not match original declaration [-Wlto-type-mismatch]
void *memset (void *, int, size_t);
^
CryptoPkg/Library/IntrinsicLib/MemoryIntrinsics.c:27:8: note: type mismatch in parameter 2
void * memset (void *dest, char ch, size_t count)
^
This commit changes the type of ch from char to int to match the
declaration.
