Subject: modpost: free allocated memory
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c7d47f26df949f0031fe2905068ee85db1b63ed9;p=linux.git

modpost: free allocated memory

valgrind complains that memory is not freed after allocation
with realloc() called from main() and write_dump().

So let us free the allocated memory properly.
