gpio: em: Use irq_domain_add_simple() to fix runtime error
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 Cc: stable@kernel.org Signed-off-by: Magnus Damm <damm@opensource.se> Tested-by: Simon Horman <horms+renesas@verge.net.au> Reported-by: Simon Horman <horms+renesas@verge.net.au> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
