Introduce the irq_read_line() function to allow device drivers to read the current logical state of an input when the hardware only exposes this through status bits in the interrupt controller. The new function is backed by a new callback function in the irq_chip - irq_read_line() - that can be implemented by irq_chips that owns such status bits. Based on rfc patch from April 2011 by Abhijeet. Cc: Abhijeet Dharmapurikar <redacted> Signed-off-by: Bjorn Andersson <redacted>
