There is a plan to build the kernel with -Wimplicit-fallthrough and this place in the code produced a warning (W=1).
In this particular case rewrote the comment to start with the string "fall through", so as to match the regular expression expected by GCC. This commit remove the following warning: drivers/firewire/core-iso.c:308:7: warning: this statement may fall through [-Wimplicit-fallthrough=] Signed-off-by: Mathieu Malaterre <ma...@debian.org> --- drivers/firewire/core-iso.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/firewire/core-iso.c b/drivers/firewire/core-iso.c index 35e784cffc23..d2d50bda5a5f 100644 --- a/drivers/firewire/core-iso.c +++ b/drivers/firewire/core-iso.c @@ -308,7 +308,7 @@ static int manage_channel(struct fw_card *card, int irm_id, int generation, if ((data[0] & bit) == (data[1] & bit)) continue; - /* 1394-1995 IRM, fall through to retry. */ + /* fall through - 1394-1995 IRM to retry. */ default: if (retry) { retry--; -- 2.19.2
