[PATCH v2 0/4] lib: sbi: fwft: Fix return error values according to the spec

[Clément Léger]

The fwft spec mandates that an invalid feature ID return
SBI_ERR_INVALID_PARAM and that setting a locked value should return
SBI_ERR_DENIED_LOCKED. Add support for both cases.

---
v2:
 - Use BIT_ULL instead of BIT to avoid shift overflow.
 - Include another patch to optimize flags clearing.

Clément Léger (4):
  include: sbi: Add SBI_ERR_DENIED_LOCKED
  lib: sbi: fwft: Return SBI_ERR_DENIED_LOCKED when setting a locked
    feature
  lib: sbi: fwft: Fix error return value for feature > 32 bits
  lib: sbi: Clear lock only for local events
