rtllib_is_shortslot() takes one argument - a struct that's more than a kilobyte large. It should take a pointer instead of copying such a huge struct - and the argument might as well be declared 'const' now that we are at it, since it is not modified. This patch makes these changes. Signed-off-by:

If ibss_wlan is NULL, it is not correct to memcpy into its field. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ expression E, E1; identifier f; statement S1,S2,S3; @@ if (E == NULL) { ... when != if (E == NULL || ...)

This patch releases semaphore locks when an error occurrs while attempting to download firmware for the bcm driver. When downloading firmware for this driver, a process is expected to call the following ioctl's in this order: (1)IOCTL_BCM_BUFFER_DOWNLOAD_START, (2)IOCTL_BCM_BUFFER_DOWNLOAD, and (3) IOCTL_BCM_BUFFER_DOWNLOAD_STOP. Semaphore, “Adapter->fw_download_sema” is expected to be acquired in the first ioctl, IOCTL_BCM_BUFFER_DOWNLOAD_START, and it should block until IOCTL_BCM_BUFFER_DOWNLOAD_STOP is called. In this case, if an error occurred before STOP finished, the semaphore "Adapter->fw_download_sema" was not being released. Signed-off-by:

In this ioctl, we are testing to see if the lock is held. If it is not held, that means this ioctl used incorrectly. Therefore, we do not want to take the lock ourselves here. Signed-off-by:

This patch verifies two conditions before executing a kmalloc call. First, it checks to see that IoBuffer.OutputLength is not greater than an unsigned short. If so, an invalid value may be returned. The second change is a check to make sure IoBuffer.OutputLength is not equal to zero. Which simply keeps this code inline with the other ioctl, IOCTL_BCM_REGISTER_READ_PRIVATE. Signed-off-by:

Staging: bcm: Fix information leak in ioctl: IOCTL_BCM_REGISTER_READ_PRIVATE, IOCTL_BCM_EEPROM_REGISTER_READ This patch fixes an information leak in ioctl IOCTL_BCM_REGISTER_READ_PRIVATE and IOCTL_BCM_EEPROM_REGISTER_READ when determining the number of bytes to copy to user space. Function, usb_control_msg, returns the correct number of bytes from the hardware. Instead of using this value, we were using a value derived from user space. In this case, this value could be more than the hardware allocated. Therefore, this patch copies the proper number of bytes from the hardware, and uses this value as the maximum number of bytes for user space. Signed-off-by:

If the dummy evgen failed init, the irq allocation functions which assume init succeeded may still be called - causing an OOPS due to wrong assumption.

Quite a few iio drivers provide no MODULE_DEVICE_TABLE or MODULE_ALIAS or only provide a MODULE_ALIAS while they have support for multiple device ids. This prevents auto module loading from working correctly. This patch fixes it by adding the missing MODULE_DEVICE_TABLEs and MODULE_ALIAS'. Signed-off-by:
