csky: fix syscache.c fallthrough warning
[ Upstream commit 0679d29d3e2351a1c3049c26a63ce1959cad5447 ]
This case of the switch statement falls through to the following case.
This appears to be on purpose, so declare it as OK.
../arch/csky/mm/syscache.c: In function '__do_sys_cacheflush':
../arch/csky/mm/syscache.c:17:3: warning: this statement may fall through [-Wimplicit-fallthrough=]
17 | flush_icache_mm_range(current->mm,
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
18 | (unsigned long)addr,
| ~~~~~~~~~~~~~~~~~~~~
19 | (unsigned long)addr + bytes);
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
../arch/csky/mm/syscache.c:20:2: note: here
20 | case DCACHE:
| ^~~~
Fixes: 997153b9a75c ("csky: Add flush_icache_mm to defer flush icache all")
