4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Franck Demathieu <fdemathieu@xxxxxxxxx>
[ 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>
