Use the new helper devm_platform_ioremap_resource() which wraps the
platform_get_resource() and devm_ioremap_resource() together, to
simplify the code.Signed-off-by: Anson Huang

gcc points out that irqs_num is not initialized when of_property_read_u32()
is an empty stub function:Included from drivers/irqchip/irq-imx-irqsteer.c:7:
drivers/irqchip/irq-imx-irqsteer.c: In function 'imx_irqsteer_probe':
include/uapi/linux/kernel.h:13:49: error: 'irqs_num' may be used uninitialized in this function [-Werror=maybe-uninitialized]The same can actually happen with CONFIG_OF=y as well, though we don't
get a warning then.Add error checking here that lets the code deal with missing or
invalid properties as well as avoid the warning.Fixes: 28528fca4908 ("irqchip/imx-irqsteer: Add multi output interrupts support")

One group can manage 64 interrupts by using two registers (e.g. STATUS/SET).
However, the integrated irqsteer may support only 32 interrupts which
needs only one register in a group. But the current driver assume there's
a mininum of two registers in a group which result in a wrong register map
for 32 interrupts per channel irqsteer. Let's use the reg_num caculated by
interrupts per channel instead of irq_group to cover this case.Cc: Rob Herring
