2025-06-19fpga: fix potential null pointer deref in fpga_mgr_test_img_load_sgt()Qasim Ijaz
[ Upstream commit 6ebf1982038af12f3588417e4fd0417d2551da28 ] fpga_mgr_test_img_load_sgt() allocates memory for sgt using kunit_kzalloc() however it does not check if the allocation failed. It then passes sgt to sg_alloc_table(), which passes it to __sg_alloc_table(). This function calls memset() on sgt in an attempt to zero it out. If the allocation fails then sgt will be NULL and the memset will trigger a NULL pointer dereference. Fix this by checking the allocation with KUNIT_ASSERT_NOT_ERR_OR_NULL().

2024-08-14fpga: Simplify and improve fpga mgr test using deferred actionsMarco Pagani
Use deferred actions to simplify the test suite and avoid potential memory leaks when test cases fail. Remove unnecessary calls to kunit_device_unregister() since kunit devices are tied to the test context and released by a deferred action when the test is completed.

2024-04-09fpga: tests: use KUnit devices instead of platform devicesMarco Pagani
KUnit now provides helper functions to create fake devices, so use them instead of relying on platform devices. Other changes: remove an unnecessary white space in the fpga region suite.
