263 struct chipset_power_state *ps;
264
265 ps = pmc_get_power_state();

CID 1396443: Error handling issues (CHECKED_RETURN)

/src/lib/selfboot.c: 263 in _selfload()

258 cbfssegs = &((struct cbfs_payload *)data)->segments;
259
260 if (f && f(cbfssegs))
261 goto out;

CID 1396442: Memory - corruptions (ARRAY_VS_SINGLETON)
Passing "cbfssegs" to function "load_payload_segments" which uses it as an array. This might corrupt or misinterpret adjacent memory locations.

263 if (load_payload_segments(cbfssegs, &entry))
264 goto out;
265
266 printk(BIOS_SPEW, "Loaded segments\n");
