Jia-Ju Bai 6499a0db9b media: pci: ttpci: av7110: fix possible buffer overflow caused by bad DMA value in debiirq() 
The value av7110->debi_virt is stored in DMA memory, and it is assigned
to data, and thus data[0] can be modified at any time by malicious
hardware. In this case, "if (data[0] < 2)" can be passed, but then
data[0] can be changed into a large number, which may cause buffer
overflow when the code "av7110->ci_slot[data[0]]" is used.

To fix this possible bug, data[0] is assigned to a local variable, which
replaces the use of data[0].

/* Budgetpatch note:
* Original hardware design by Roberto Deza:
* There is a DVB_Wiki at
* https://linuxtv.org
*
* New software triggering design by Emard that works on
* original Roberto Deza's hardware:
*
* rps1 code for budgetpatch will copy internal HS event to GPIO3 pin.
* GPIO3 is in budget-patch hardware connectd to port B VSYNC
* HS is an internal event of 7146, accessible with RPS
* and temporarily raised high every n lines
* (n in defined in the RPS_THRESH1 counter threshold)
* I think HS is raised high on the beginning of the n-th line
* and remains high until this n-th line that triggered
* it is completely received. When the reception of n-th line
* ends, HS is lowered.
*
* To transmit data over DMA, 7146 needs changing state at
* port B VSYNC pin. Any changing of port B VSYNC will
* cause some DMA data transfer, with more or less packets loss.
* It depends on the phase and frequency of VSYNC and
* the way of 7146 is instructed to trigger on port B (defined
* in DD1_INIT register, 3rd nibble from the right valid
* numbers are 0-7, see datasheet)
*
* The correct triggering can minimize packet loss,
* dvbtraffic should give this stable bandwidths:
* 22k transponder = 33814 kbit/s
* 27.5k transponder = 38045 kbit/s
* by experiment it is found that the best results
* (stable bandwidths and almost no packet loss)
* are obtained using DD1_INIT triggering number 2
* (Va at rising edge of VS Fa = HS x VS-failing forced toggle)
* and a VSYNC phase that occurs in the middle of DMA transfer
* (about byte 188*512=96256 in the DMA window).
*
* Phase of HS is still not clear to me how to control,
* It just happens to be so. It can be seen if one enables
* RPS_IRQ and print Event Counter 1 in vpeirq(). Every
* time RPS_INTERRUPT is called, the Event Counter 1 will
* increment. That's how the 7146 is programmed to do event
* counting in this budget-patch.c
* I *think* HPS setting has something to do with the phase
* of HS but I can't be 100% sure in that.
*
* hardware debug note: a working budget card (including budget patch)
* with vpeirq() interrupt setup in mode "0x90" (every 64K) will
* generate 3 interrupts per 25-Hz DMA frame of 2*188*512 bytes
* and that means 3*25=75 Hz of interrupt frequency, as seen by
* watch cat /proc/interrupts
*
* If this frequency is 3x lower (and data received in the DMA
* buffer don't start with 0x47, but in the middle of packets,
* whose lengths appear to be like 188 292 188 104 etc.
* this means VSYNC line is not connected in the hardware.
* (check soldering pcb and pins)
* The same behaviour of missing VSYNC can be duplicated on budget
* cards, by setting DD1_INIT trigger mode 7 in 3rd nibble.
