[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [XEN PATCH v2] x86/HVM: address violations of MISRA C:2012 Rules 8.2 and 8.3
Give a name to unnamed parameters thus addressing violations of
MISRA C:2012 Rule 8.2 ("Function types shall be in prototype form with
named parameters").
Keep consistency between parameter names and types used in function
declarations and the ones used in the corresponding function
definitions, thus addressing violations of MISRA C:2012 Rule 8.3
("All declarations of an object or function shall use the same names
and type qualifiers").
No functional changes.
Signed-off-by: Federico Serafini <federico.serafini@xxxxxxxxxxx>
---
Changes in v2:
- u64 vs uint64_t mismatches are solved in favor of the stdint types.
