If one statement in the loops / conditional statement then it does not matter u are putiing braces or not.

But strong recommendation is that put braces like this

expression ;

In all excellent industries recommend this.
Use of it is that No Confusion( If big and too much complex single expression) and easy to see the values by debugging)


AgprsLink_mp = (AgprsMotLink *) ( InputDataSubLink) *Function(agprs_val,
(PcmLinkDataRes_m *)( nData),
(PacketFormet_m* ) (nLink) );

this is simple case, I did'nt remember, I saw manyplace too much complex sinlgle expression and it will be confusion. So better use braces for any loop with a single or more than one statements.
