media: cx88-mpeg: clear interrupt status register before streaming video
[ Upstream commit 56cb61f70e547e1b0cdfe6ff5a1f1ce6242e6d96 ]
Some cx88 video cards may have transport stream status interrupts set
to 1 from cold start, causing errors like this:
cx88xx: cx88_print_irqbits: core:irq mpeg [0x100000] ts_err?*
cx8802: cx8802_mpeg_irq: mpeg:general errors: 0x00100000
According to CX2388x datasheet, the interrupt status register should be
cleared before enabling IRQs to stream video.
Fix it by clearing the Transport Stream Interrupt Status register.
