2012-10-06[media] rc: divide by zero bugs in s_tx_carrier()Dan Carpenter3-1/+10
"carrier" comes from a get_user() in ir_lirc_ioctl(). We need to test that it's not zero before using it as a divisor. It might have been nice to test for this ir_lirc_ioctl() but the mceusb driver uses zero to disable carrier modulation. The bug in redrat3 is a little more subtle. The ->carrier is passed to mod_freq_to_val() which uses it as a divisor. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2012-10-05[media] videobuf2-core: move plane verification out of __fill_v4l2/vb_bufferHans Verkuil1-40/+38
The plane verification should be done before actually queuing or dequeuing buffers, so move it out of __fill_v4l2_buffer and __fill_vb_buffer and call it as a separate step. This also makes it possible to change the return type of __fill_v4l2/vb_buffer to void. The dqbuf case took some special care: before removing a buffer from the done_list you have to verify that the receiving v4l2_buffer has enough room for all the planes. The number of planes can differ between buffers due to the fact that buffers for other formats can be prepared using VIDIOC_PREPARE_BUF.
