irqchip/crossbar: Fix incorrect type of register size
The 'size' variable is unsigned according to the dt-bindings. As this variable is used as integer in other places, create a new variable that allows to fix the following sparse issue (-Wtypesign): drivers/irqchip/irq-crossbar.c:279:52: warning: incorrect type in argument 3 (different signedness) drivers/irqchip/irq-crossbar.c:279:52: expected unsigned int [usertype] *out_value drivers/irqchip/irq-crossbar.c:279:52: got int *<noident> Signed-off-by: Franck Demathieu <fdemathieu@gmail.com> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
