3.3-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sergei Shtylyov <sshtyl...@ru.mvista.com>
commit 9716387311c790de381214c03e7f1b72b91a8189 upstream.
According to the HT6560H datasheet, the recovery timing field is 4-bit wide,
with a value of 0 meaning 16 cycles. Correct obvious thinko in the recovery
field mask.
