Subject: [PATCH] Subject: x86/vdso/vdso2c: Memory Leak fix, Fix leak of variable name in vdso2c.c

The file vdso2c.c contains a memory leak of variable 'name'.
This leak was detected by ASAN(AddressSanitizer) on local  builds.
A tool called AddressWatcher automatically attempts to fix memory
leaks suggested by ASAN. The fix has been inserted to stop the
memory leak in the file vdso2c.c.
