[ Upstream commit ed69b28b3a5e39871ba5599992f80562d6ee59db ]
Running coccinelle spatch gave the following warning:
./drivers/gpu/drm/xe/tests/xe_migrate.c:226:5-11: inconsistent IS_ERR and PTR_ERR on line 228.
The code reports PTR_ERR(pt) when IS_ERR(tiny) is checked:
→ 211 pt = xe_bo_create_pin_map(xe, tile, m->q->vm, XE_PAGE_SIZE, 212 ttm_bo_type_kernel, 213 XE_BO_FLAG_VRAM_IF_DGFX(tile) | 214 XE_BO_FLAG_PINNED); 215 if (IS_ERR(pt)) { 216 KUNIT_FAIL(test, "Failed to allocate fake pt: %li\n", 217 PTR_ERR(pt)); 218 goto free_big; 219 } 220 221 tiny = xe_bo_create_pin_map(xe, tile, m->q->vm, → 222 2 * SZ_4K, 223 ttm_bo_type_kernel, 224 XE_BO_FLAG_VRAM_IF_DGFX(tile) | 225 XE_BO_FLAG_PINNED); → 226 if (IS_ERR(tiny)) { → 227 KUNIT_FAIL(test, "Failed to allocate fake pt: %li\n", → 228 PTR_ERR(pt)); 229 goto free_pt; 230 }
Now, the IS_ERR(tiny) and the corresponding PTR_ERR(pt) do not match.
Returning PTR_ERR(tiny), as the last failed function call, seems logical.
