Ard Biesheuvel e10de46bc3 tpm: Avoid function type cast of put_device() ... The TPM code registers put_device() as a devm cleanup handler, and casts the reference to the right function pointer type for this to be permitted by the compiler. However, under kCFI, this is rejected at runtime, resulting in a splat like CFI failure at devm_action_release+0x24/0x3c (target: put_device+0x0/0x24; expected type: 0xa488ebfc) Internal error: Oops - CFI: 0000000000000000 [#1] PREEMPT SMP Modules linked in: ...
