My test case is simple, simply load the driver.

The problem is that you moved the algs[i].mc = mc after the register of algs (in drivers: crypto: meson: move algs definition and cipher API to cipher.c)
Test could happen as soon the register is done and so mc is deferenced.

Since you didnt hit the case, I suspect you didnt test the driver as module.
