csky: fix syscache.c fallthrough warning
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") Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Guo Ren <guoren@kernel.org> Cc: linux-csky@vger.kernel.org Cc: Arnd Bergmann <arnd@arndb.de>
