ARM: 5635/1: Use DIV_ROUND_CLOSEST
Author: Julia Lawall <julia@diku.dk>
The kernel.h macro DIV_ROUND_CLOSEST performs the computation
(x + d/2)/d but is perhaps more readable.
The semantic patch that makes this change is as follows:
(http://www.emn.fr/x-info/coccinelle/)
//

@depends on haskernel@
expression x,__divisor;
@@
- (((x) + ((__divisor) / 2)) / (__divisor))
+ DIV_ROUND_CLOSEST(x,__divisor)
//
