Subject[PATCH] irqchip/renesas-intc-irqpin: Merge irlm_bit and needs_irlm
Date
Get rid of the separate flag to indicate if the IRLM bit is present in
the INTC/Interrupt Control Register 0, by considering -1 an invalid
irlm_bit value.

Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>

Tested on r8a7778/bock-w, r8a7779/marzen, r8a7740/armadillo. and
sh73a0/kzm9g.
