X-Git-Tag: v6.15-rc1~47^2~67

tty: serial: fsl_lpuart: Make interrupt name distinct

SoCs like the i.MX93 have several lpuart interfaces, but fsl_lpuart
uses the driver name to request the IRQ. This makes it hard to
identify interfaces from outputs like /proc/interrupts .
So use the dev_name() for requesting instead.
