Ruan Jinjie 2f54db449b irqchip/imx-mu-msi: Do not check for 0 return after calling platform_get_irq() 
It is not possible for platform_get_irq() to return 0. Use the
return value from platform_get_irq().

Frank Li 70afdab904 irqchip: Add IMX MU MSI controller driver 
The MU block found in a number of Freescale/NXP SoCs supports generating
IRQs by writing data to a register.

This enables the MU block to be used as a MSI controller, by leveraging
the platform-MSI API.
