Subject: irqchip/crossbar: Fix incorrect type of register size

From: Franck Demathieu <[email protected]>

[ Upstream commit 4b9de5da7e120c7f02395da729f0ec77ce7a6044 ]

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>
