[XEN PATCH v2] xen: use parameter name 'mcs' in arch_do_multicall_call()
Posted by Federico Serafini 9 months, 1 week ago 
Make function declaration and definition consistent using the same
parameter name ('mcs' do denote a pointer to an 'mc_state').
This addresses a violation of MISRA C:2012 Rule 8.3: "All declarations
of an object or function shall use the same names and type qualifiers".
