From: Julia Lawall <julia@xxxxxxx> Delete successive assignments to the same location. In three of the cases, the two assignments are identical. In the case of the file rt2860/common/cmm_aes.c, the assigned variable i is never used, so both assignments are dropped. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression i; @@ *i = ...; i = ...; // </smpl> Signed-off-by: Julia Lawall <julia@xxxxxxx> --- drivers/staging/ft1000/ft1000-usb/ft1000_chdev.c | 1 - drivers/staging/hv/hv_utils.c | 3 --- drivers/staging/rt2860/common/cmm_aes.c | 2 -- drivers/staging/westbridge/astoria/api/src/cyasusb.c | 1 - 4 files changed, 7 deletions(-) diff --git a/drivers/staging/ft1000/ft1000-usb/ft1000_chdev.c b/drivers/staging/ft1000/ft1000-usb/ft1000_chdev.c index 87a6487..20d5098 100644 --- a/drivers/staging/ft1000/ft1000-usb/ft1000_chdev.c +++ b/drivers/staging/ft1000/ft1000-usb/ft1000_chdev.c @@ -286,7 +286,6 @@ int ft1000_CreateDevice(struct ft1000_device *dev) pid = kernel_thread (exec_mknod, (void *)info, 0); // initialize application information - info->appcnt = 0; // if (ft1000_flarion_cnt == 0) { // diff --git a/drivers/staging/hv/hv_utils.c b/drivers/staging/hv/hv_utils.c index 702a478..a99e900 100644 --- a/drivers/staging/hv/hv_utils.c +++ b/drivers/staging/hv/hv_utils.c @@ -212,9 +212,6 @@ static void heartbeat_onchannelcallback(void *context) recvlen, requestid); icmsghdrp = (struct icmsg_hdr *)&buf[ - sizeof(struct vmbuspipe_hdr)]; - - icmsghdrp = (struct icmsg_hdr *)&buf[ sizeof(struct vmbuspipe_hdr)]; if (icmsghdrp->icmsgtype == ICMSGTYPE_NEGOTIATE) { diff --git a/drivers/staging/rt2860/common/cmm_aes.c b/drivers/staging/rt2860/common/cmm_aes.c index 1d159ff..a99879b 100644 --- a/drivers/staging/rt2860/common/cmm_aes.c +++ b/drivers/staging/rt2860/common/cmm_aes.c @@ -330,8 +330,6 @@ void construct_mic_iv(unsigned char *mic_iv, for (i = 8; i < 14; i++) mic_iv[i] = pn_vector[13 - i]; /* mic_iv[8:13] = PN[5:0] */ #endif - i = (payload_length / 256); - i = (payload_length % 256); mic_iv[14] = (unsigned char)(payload_length / 256); mic_iv[15] = (unsigned char)(payload_length % 256); diff --git a/drivers/staging/westbridge/astoria/api/src/cyasusb.c b/drivers/staging/westbridge/astoria/api/src/cyasusb.c index 5a21970..7777d9a 100644 --- a/drivers/staging/westbridge/astoria/api/src/cyasusb.c +++ b/drivers/staging/westbridge/astoria/api/src/cyasusb.c @@ -1417,7 +1417,6 @@ cy_as_usb_set_enum_config(cy_as_device_handle handle, */ bus_mask = 0; media_mask = 0; - media_mask = 0; for (bus = 0; bus < CY_AS_MAX_BUSES; bus++) { for (device = 0; device < CY_AS_MAX_STORAGE_DEVICES; device++) { if (config_p->devices_to_enumerate[bus][device] == _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/devel
