staging: comedi: drivers: Use DIV_ROUND_CLOSEST
The kernel.h macro DIV_ROUND_CLOSEST performs the computation (x + d/2)/d
but is perhaps more readable.
The Coccinelle script used:
// <smpl>
@haskernel@
@@
@depends on haskernel@
expression x,__divisor;
@@
- (((x) + ((__divisor) / 2)) / (__divisor))
+ DIV_ROUND_CLOSEST(x,__divisor)
// </smpl>
