USB: Fix a memory leak in em28xx_usb_probe()
If, in em28xx_usb_probe() the memory allocation dev->alt_max_pkt_size = kmalloc(32* dev->num_alt,GFP_KERNEL); fails, then we'll bail out and return -ENOMEM. The problem is that in that case we don't free the storage allocated to 'dev', thus causing a memory leak. This patch fixes the leak by freeing 'dev' before we return -ENOMEM. This fixes Coverity bug #647. Signed-off-by: Jesper Juhl <jesper.juhl@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
