From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx> Current usbhs_for_each_dfifo macro will read out-of-array's memory after last loop operation. It was not good C language operation, and the binary which was compiled by (at least) gcc 4.8.1 is broken. This patch is based on 925403f425a4a9c503f2fc295652647b1eb10d82 (usb: renesas_usbhs: tidyup original usbhsx_for_each_xxx macro) Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx> Tested-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@xxxxxxxxxxx> --- >> Felip eoriginal patch was posted in Subject: [PATCH][RFC] usb: renesas_usbhs: tidyup usbhs_for_each_dfifo macro Date: Fri, 3 Apr 2015 00:42:53 +0000 This is non RFC version drivers/usb/renesas_usbhs/fifo.h | 9 +++++---- 1 file changed, 5 insertions(+), 4 deletions(-) diff --git a/drivers/usb/renesas_usbhs/fifo.h b/drivers/usb/renesas_usbhs/fifo.h index 04d3f8a..c7d9b86 100644 --- a/drivers/usb/renesas_usbhs/fifo.h +++ b/drivers/usb/renesas_usbhs/fifo.h @@ -44,10 +44,11 @@ struct usbhs_fifo_info { struct usbhs_fifo dfifo[USBHS_MAX_NUM_DFIFO]; }; #define usbhsf_get_dnfifo(p, n) (&((p)->fifo_info.dfifo[n])) -#define usbhs_for_each_dfifo(priv, dfifo, i) \ - for ((i) = 0, dfifo = usbhsf_get_dnfifo(priv, (i)); \ - ((i) < USBHS_MAX_NUM_DFIFO); \ - (i)++, dfifo = usbhsf_get_dnfifo(priv, (i))) +#define usbhs_for_each_dfifo(priv, dfifo, i) \ + for ((i) = 0; \ + ((i) < USBHS_MAX_NUM_DFIFO) && \ + ((dfifo) = usbhsf_get_dnfifo(priv, (i))); \ + (i)++) struct usbhs_pkt_handle; struct usbhs_pkt { -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
