Staging: rtl8192e: rtl_core: Constify rtllib_qos_parameters structures
Declare the structure rtllib_qos_parameters as constant as it is only
passed as the second argument to the function memcpy. This argument
is constant so the fields of rtllib_qos_parameters structure are
never modified and hence it can be declared as const.
Done using coccinelle:
@r1 disable optional_qualifier @
identifier i;
position p;
@@
static struct rtllib_qos_parameters i@p = {...};
@ok1@
identifier r1.i;
position p;
expression e1,e2;

memcpy(e1,&i@p,e2)
@bad@
position p!={r1.p,ok1.p};
