media: ite-cir: IR receiver stop working after receive overflow
commit
fdc881783099c6343921ff017450831c8766d12a upstream.
On an Intel NUC6iSYK, no IR is reported after a receive overflow.
When a receiver overflow occurs, this condition is only cleared by
reading the fifo. Make sure we read anything in the fifo.
Fixes:
