--------------------------------

[ Upstream commit b776c4a4 ]

There may be failure when start 1 channel recording after
8 channels recording. The reason is that the CHnF
flags are not cleared successfully by software reset.

This issue is triggerred by the change of clearing
software reset bit.

CHnF flags are write 1 clear bits. Clear them by force
write.
