Subject: [PATCH] ASoC: rt5651: Use IRQF_NO_AUTOEN when requesting the IRQ
Git-commit: 6e037b72cf4ea6c28a131ea021d63ee4e7e6fa64
Patch-mainline: v5.16-rc1
References: git-fixes

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.
