commit 8137355e850f ("aspeed/timer: Fix behaviour running Linux")
introduced a MAX() expression to calculate the next timer deadline :
return calculate_time(t, MAX(MAX(t->match[0], t->match[1]), 0));
The second MAX() is not necessary since the compared values are an
unsigned and 0. Simply remove it and fix warning :
../hw/timer/aspeed_timer.c: In function ‘calculate_next’:
../include/qemu/osdep.h:396:31: warning: declaration of ‘_a’ shadows a
