[PATCH 5.15 040/279] ASoC: rt5651: Use IRQF_NO_AUTOEN when requesting the IRQ

From: Hans de Goede <hdegoede@redhat.com>

[ Upstream commit 6e037b72cf4ea6c28a131ea021d63ee4e7e6fa64 ]

Use the new IRQF_NO_AUTOEN flag when requesting the IRQ, rather then
disabling it immediately after requesting it.

This fixes a possible race where the IRQ might trigger between requesting
and disabling it; and this also leads to a small code cleanup.
