3.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Magnus Damm <damm@xxxxxxxxxxxxx>
commit c7886b18273b07042e25e8d3ba5c983837b84123 upstream.
Adjust the gpio-em.c driver to reconsider the pdata->irq_base
variable. Non-DT board code like for instance board-kzm9d.c
needs to operate of a static IRQ range for platform devices.
So this patch is updating the code to make use of the function
irq_domain_add_simple() instead of irq_domain_add_linear().
Fixes a EMEV2 / KZM9D runtime error caused by the following commit:
7385500 gpio/em: convert to linear IRQ domain
