During context initialisation a table of elements is dynamically allocated by fwk_mm_alloc() and the returned pointer is validated. It's been some time since we added a trap in fwk_mm_alloc(), therefore no need for pointer validation anymore. Remove such redundant check. Change-Id: Ibbbe50...

null pointer assignment 中文意思是”空指针赋值“ 或者 ”指针没有赋值“通常在编程c语言，当指针变量刚定义时，它的值是不确定的，因而指向一个不正确的单元，若在这个时候引用指针变量，可能产生不可预料的后果。为了避免这个问题的产生，定义后给它一个确定的地址值。其中pointer [英][ˈ...
