[PATCH -next] tty: serial: xilinx_uartps: Do not check for 0 return after calling platform_get_irq()
From: Ruan Jinjie <hidden>

Subsystem:
the rest, tty layer and serial drivers · Maintainers:
Linus Torvalds, Greg Kroah-Hartman, Jiri Slaby
Since commit a85a6c86c25b ("driver core: platform: Clarify that
IRQ 0 is invalid"), there is no possible for
platform_get_irq() to return 0. Use the return value
from platform_get_irq().
