Category: Incorrect expression
Function: test_k_aligned_alloc
Component: Tests
CID: 216787

Details:

97          * alignment. The backing allocator would naturally round up to
98          * some minimal block size. This would make k_aligned_alloc()
99          * more like posix_memalign() instead of aligned_alloc(), but
100          * the benefit is that k_malloc() can then just be a wrapper
101          * around k_aligned_alloc().
102          */
>>>     CID 216787:  Incorrect expression  (SIZEOF_MISMATCH)
>>>     Passing argument "4U /* sizeof (void *) */" to function "k_aligned_alloc" which returns a value of type "void *" is suspicious.
103         r = k_aligned_alloc(sizeof(void *), 1);
104         /* allocation succeeds */
105         zassert_not_equal(NULL, r, "aligned alloc of 1 byte failed");
106         /* r is suitably aligned */
107         zassert_equal(0, (uintptr_t)r % sizeof(void *),
108             "%p not %u-byte-aligned",
