[Xen-devel] [PATCH] xen/arm: timer: Don't warn if the timer interrupts are high-level

[Julien Grall <julien.grall@xxxxxxxxxx>]

The commit 61d6a84 "xen: arm: Warn if timer interrupts are not level
triggered" added a check to ensure the timer interrupts are level.

Although, the check is only done on low-level interrupts. This will
result to a strange warning on platform using high-level ("WARNING [..]
IRQ is not level triggered").

As high-level interrupt is valid, don't warn on both high-level and
low-level interrupt.

The Seattle DT is using high-level interrupt. Also I haven't tried to
boot the latest Xen on it...
