This was already done in the error check, so this block was replaced with
"/* texsubimage_error_check ensures that texImage is not NULL */."

It's added in patch 38 in the form "if (!texObj)\n return;" (The invalid
operation error does not need to be thrown for texsubimage because it does
not use the user's texture_name to look up the texture object in the hash
table.)
