[PATCH 4.4 055/105] irqchip/crossbar: Fix incorrect type of register size

[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

[ 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>
