[ Upstream commit d3efd26af2e044ff2b48d38bb871630282d77e60 ]
The probe calls 'wcd9335_setup_irqs()' to enable interrupts on all slave ports. This must be undone in the remove function.
Add a 'wcd9335_teardown_irqs()' function that undoes 'wcd9335_setup_irqs()' function, and call it from the remove function.
