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.
