- kfree is being called for the members of the queue without de-queuing them; they are just inserted within this function; they are supposed to be de-queued and freed in a function for receiving the queue items - goto statements are removed - After kfree correction, there is no need for target block of goto statement; hence it is removed Signed-off-by: Chandra S Gorentla <csgorentla@xxxxxxxxx> --- drivers/staging/wilc1000/wilc_msgqueue.c | 22 ++++++---------------- 1 file changed, 6 insertions(+), 16 deletions(-) diff --git a/drivers/staging/wilc1000/wilc_msgqueue.c b/drivers/staging/wilc1000/wilc_msgqueue.c index 284a3f5..eae90be 100644 --- a/drivers/staging/wilc1000/wilc_msgqueue.c +++ b/drivers/staging/wilc1000/wilc_msgqueue.c @@ -56,32 +56,30 @@ int wilc_mq_destroy(WILC_MsgQueueHandle *pHandle) int wilc_mq_send(WILC_MsgQueueHandle *pHandle, const void *pvSendBuffer, u32 u32SendBufferSize) { - int result = 0; unsigned long flags; Message *pstrMessage = NULL; if ((!pHandle) || (u32SendBufferSize == 0) || (!pvSendBuffer)) { PRINT_ER("pHandle or pvSendBuffer is null\n"); - result = -EFAULT; - goto ERRORHANDLER; + return -EFAULT; } if (pHandle->bExiting) { PRINT_ER("pHandle fail\n"); - result = -EFAULT; - goto ERRORHANDLER; + return -EFAULT; } /* construct a new message */ pstrMessage = kmalloc(sizeof(Message), GFP_ATOMIC); if (!pstrMessage) return -ENOMEM; + pstrMessage->u32Length = u32SendBufferSize; pstrMessage->pstrNext = NULL; pstrMessage->pvBuffer = kmalloc(u32SendBufferSize, GFP_ATOMIC); if (!pstrMessage->pvBuffer) { - result = -ENOMEM; - goto ERRORHANDLER; + kfree(pstrMessage); + return -ENOMEM; } memcpy(pstrMessage->pvBuffer, pvSendBuffer, u32SendBufferSize); @@ -102,15 +100,7 @@ int wilc_mq_send(WILC_MsgQueueHandle *pHandle, spin_unlock_irqrestore(&pHandle->strCriticalSection, flags); up(&pHandle->hSem); - -ERRORHANDLER: - /* error occured, free any allocations */ - if (pstrMessage) { - kfree(pstrMessage->pvBuffer); - kfree(pstrMessage); - } - - return result; + return 0; } /*! -- 2.1.4 _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
