4.11-stable review patch. If anyone has any objections, please let me know.
------------------ From: Tony Lindgren <[email protected]> commit 5a88d4120029601a0868e20774382d312952d3b5 upstream. We should use ack_invert as the int_read_and_clear() in the Motorola kernel tree does "ireg_val & ~mreg_val" before writing to the mask register.
