usercopy: Add parentheses around assignment in test_copy_struct_from_user
Clang warns: lib/test_user_copy.c:96:10: warning: using the result of an assignment as a condition without parentheses [-Wparentheses] if (ret |= test(umem_src == NULL, "kmalloc failed")) ~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ lib/test_user_copy.c:96:10: note: place parentheses around the assignment to silence this warning if (ret |= test(umem_src == NULL, "kmalloc failed")) ^ ( ) lib/test_user_copy.c:96:10: note: use '!=' to turn this compound assignment into an inequality comparison if (ret |= test(umem_src == NULL, "kmalloc failed")) ^~ != Add the parentheses as it suggests because this is intentional.
