CEC_MSG_REPORT_PHYSICAL_ADDR can theoretically be received from an unregistered device, but in that case the code should not attempt to write the received physical address to the phys_addrs array. That would be pointless since there can be multiple unregistered devices that report a physical address. We just ignore those. While at it, improve the dprintk since it would attempt to read from that array as well with the same out-of-bounds problem. Signed-off-by:

There is a rudimentary ISR for handling interrupts generated by the wakeup part of the chip. Interrupts however have never been enabled in the wakeup part. Also, now that we can set the wakeup sequence via sysfs, there's in general no need to enable interrupts in the wakeup part. Signed-off-by:

To detect a rx fifo overrun it's checked whether the number of elements in the chip fifo exceeds the fifo size. This check can never return true and is wrong. Instead we should generate an interrupt if the fifo overruns. Signed-off-by:

DiSEqC message sending takes 13.5 ms per byte, which is 54 ms total when typical 4 byte message is sent. Don't hard-code time limit to 54 ms, but calculate it. Time limit is only used to determine when to start poll "DiSEqC Tx ready" status from the chip. Signed-off-by:

Si2168-B40 firmware API has changed somewhere between 4.0-11 and 4.0-19 so that sleep will lose firmware upgrade from the chip. Due to that firmware re-upload is needed when newer firmwares are used. Rewrote firmware handling logic partly at the same. Signed-off-by:

The part can be reset by a low pulse on the RESET pin (i.e. a hardware reset) with a minimum width of 5 ms. It is recommended to wait 5 ms after the low pulse before an I2C write is performed to the part. For safety reasons, the delays will be between 5 and 10 ms. The RESET pin can be tied high, so the GPIO is optional. Signed-off-by:

The dvb demuxer code uses a 'struct timespec' to pass a timeout as absolute time. This will cause problems on 32-bit architectures in 2038 when time_t overflows, and it is racy with a concurrent settimeofday() call. This patch changes the code to use ktime_get() instead, using the monotonic time base to avoid both the race and the overflow. Signed-off-by:

According to the doc, V4L2_BUF_FLAG_DONE is cleared after DQBUF: V4L2_BUF_FLAG_DONE 0x00000004 ... After calling the VIDIOC_QBUF or VIDIOC_DQBUF it is always cleared ... Unfortunately, it seems that videobuf2 keeps it set after DQBUF. This can be tested with vivid and dev_debug: [257604.338082] video1: VIDIOC_DQBUF: 71:33:25.00260479 index=3, type=vid-cap, flags=0x00002004, field=none, sequence=163, memory=userptr, bytesused=460800, offset/userptr=0x344b000, length=460800 This patch forces FLAG_DONE to 0 after calling DQBUF.
