ARC: kgdb: add 'fallthrough' to prevent a warning
Use the 'fallthrough' macro to document that this switch case does indeed fall through to the next case. ../arch/arc/kernel/kgdb.c: In function 'kgdb_arch_handle_exception': ../arch/arc/kernel/kgdb.c:141:6: warning: this statement may fall through [-Wimplicit-fallthrough=] 141 | if (kgdb_hex2long(&ptr, &addr)) | ^ ../arch/arc/kernel/kgdb.c:144:2: note: here 144 | case 'D': | ^~~~ Cc: linux-snps-arc@lists.infradead.org Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
