MIPS: sni: Fix the build
[ Upstream commit c91cf42f61dc77b289784ea7b15a8531defa41c0 ]
This patch fixes the following gcc 10 build error:
arch/mips/sni/time.c: In function ‘a20r_set_periodic’:
arch/mips/sni/time.c:15:26: error: unsigned conversion from ‘int’ to ‘u8’ {aka ‘volatile unsigned char’} changes value from ‘576’ to ‘64’ [-Werror=overflow]
15 | #define SNI_COUNTER0_DIV ((SNI_CLOCK_TICK_RATE / SNI_COUNTER2_DIV) / HZ)
| ^
arch/mips/sni/time.c:21:45: note: in expansion of macro ‘SNI_COUNTER0_DIV’
21 | *(volatile u8 *)(A20R_PT_CLOCK_BASE + 0) = SNI_COUNTER0_DIV;
