This patch reduces the kernel size by removing error messages that duplicate the normal OOM message.
A simplified version of the semantic patch that finds this problem is as follows: (http://coccinelle.lip6.fr) @@ identifier f,print,l; expression e; constant char[] c; @@ e = \(kzalloc\|kmalloc\|devm_kzalloc\|devm_kmalloc\)(...); if (e == NULL) { <+... - print(...,c,...); ... when any ( goto l; | return ...; ) ...+> } Signed-off-by: Quentin Lambert <lambert.quen...@gmail.com> --- drivers/staging/rtl8723au/hal/rtl8723a_cmd.c | 8 ++------ drivers/staging/rtl8723au/hal/rtl8723a_hal_init.c | 8 ++------ drivers/staging/rtl8723au/hal/usb_ops_linux.c | 6 +----- drivers/staging/rtl8723au/os_dep/ioctl_cfg80211.c | 5 ----- 4 files changed, 5 insertions(+), 22 deletions(-) diff --git a/drivers/staging/rtl8723au/hal/rtl8723a_cmd.c b/drivers/staging/rtl8723au/hal/rtl8723a_cmd.c index 7b56411..38f5b7f 100644 --- a/drivers/staging/rtl8723au/hal/rtl8723a_cmd.c +++ b/drivers/staging/rtl8723au/hal/rtl8723a_cmd.c @@ -462,10 +462,8 @@ static void SetFwRsvdPagePkt(struct rtw_adapter *padapter, bool bDLFinished) DBG_8723A("%s\n", __func__); ReservedPagePacket = kzalloc(1000, GFP_KERNEL); - if (ReservedPagePacket == NULL) { - DBG_8723A("%s: alloc ReservedPagePacket fail!\n", __func__); + if (ReservedPagePacket == NULL) return; - } pHalData = GET_HAL_DATA(padapter); pxmitpriv = &padapter->xmitpriv; @@ -669,10 +667,8 @@ static void SetFwRsvdPagePkt_BTCoex(struct rtw_adapter *padapter) DBG_8723A("+%s\n", __func__); ReservedPagePacket = kzalloc(1024, GFP_KERNEL); - if (ReservedPagePacket == NULL) { - DBG_8723A("%s: alloc ReservedPagePacket fail!\n", __func__); + if (ReservedPagePacket == NULL) return; - } pHalData = GET_HAL_DATA(padapter); pxmitpriv = &padapter->xmitpriv; diff --git a/drivers/staging/rtl8723au/hal/rtl8723a_hal_init.c b/drivers/staging/rtl8723au/hal/rtl8723a_hal_init.c index a5eadd4..6d50b09 100644 --- a/drivers/staging/rtl8723au/hal/rtl8723a_hal_init.c +++ b/drivers/staging/rtl8723au/hal/rtl8723a_hal_init.c @@ -401,10 +401,8 @@ hal_ReadEFuse_WiFi(struct rtw_adapter *padapter, } efuseTbl = kmalloc(EFUSE_MAP_LEN_8723A, GFP_KERNEL); - if (efuseTbl == NULL) { - DBG_8723A("%s: alloc efuseTbl fail!\n", __func__); + if (efuseTbl == NULL) return; - } /* 0xff will be efuse default value instead of 0x00. */ memset(efuseTbl, 0xFF, EFUSE_MAP_LEN_8723A); @@ -494,10 +492,8 @@ hal_ReadEFuse_BT(struct rtw_adapter *padapter, } efuseTbl = kmalloc(EFUSE_BT_MAP_LEN, GFP_KERNEL); - if (efuseTbl == NULL) { - DBG_8723A("%s: efuseTbl malloc fail!\n", __func__); + if (efuseTbl == NULL) return; - } /* 0xff will be efuse default value instead of 0x00. */ memset(efuseTbl, 0xFF, EFUSE_BT_MAP_LEN); diff --git a/drivers/staging/rtl8723au/hal/usb_ops_linux.c b/drivers/staging/rtl8723au/hal/usb_ops_linux.c index a6d16ad..f1e9202 100644 --- a/drivers/staging/rtl8723au/hal/usb_ops_linux.c +++ b/drivers/staging/rtl8723au/hal/usb_ops_linux.c @@ -256,12 +256,8 @@ static void usb_read_interrupt_complete(struct urb *purb) c2w = kmalloc(sizeof(struct evt_work), GFP_ATOMIC); - if (!c2w) { - printk(KERN_WARNING "%s: unable to " - "allocate work buffer\n", - __func__); + if (!c2w) goto urb_submit; - } c2w->adapter = padapter; INIT_WORK(&c2w->work, rtw_evt_work); diff --git a/drivers/staging/rtl8723au/os_dep/ioctl_cfg80211.c b/drivers/staging/rtl8723au/os_dep/ioctl_cfg80211.c index 537bd82..40bdf4b 100644 --- a/drivers/staging/rtl8723au/os_dep/ioctl_cfg80211.c +++ b/drivers/staging/rtl8723au/os_dep/ioctl_cfg80211.c @@ -1327,8 +1327,6 @@ static int rtw_cfg80211_set_probe_req_wpsp2pie(struct rtw_adapter *padapter, pmlmepriv->wps_probe_req_ie = kmemdup(wps_ie, wps_ie[1], GFP_KERNEL); if (pmlmepriv->wps_probe_req_ie == NULL) { - DBG_8723A("%s()-%d: kmalloc() ERROR!\n", - __func__, __LINE__); return -EINVAL; } pmlmepriv->wps_probe_req_ie_len = wps_ie[1]; @@ -2619,8 +2617,6 @@ static int rtw_cfg80211_add_monitor_if(struct rtw_adapter *padapter, char *name, /* wdev */ mon_wdev = kzalloc(sizeof(struct wireless_dev), GFP_KERNEL); if (!mon_wdev) { - DBG_8723A("%s(%s): allocate mon_wdev fail\n", __func__, - padapter->pnetdev->name); ret = -ENOMEM; goto out; } @@ -3275,7 +3271,6 @@ int rtw_wdev_alloc(struct rtw_adapter *padapter, struct device *dev) /* wdev */ wdev = kzalloc(sizeof(struct wireless_dev), GFP_KERNEL); if (!wdev) { - DBG_8723A("Couldn't allocate wireless device\n"); ret = -ENOMEM; goto free_wiphy; } -- 1.9.1 _______________________________________________ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
