Subject: of/irq: init struct resource to 0 in of_irq_to_resource()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cf9e2368655d86cd800e4d9fe65a407b39d29373;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

of/irq: init struct resource to 0 in of_irq_to_resource()

It almost does not matter because most users use only the ->start member
of the struct. However if this struct is passed to a platform device
which is then added via platform_device_add() then the ->parent member is
also used.
