Subject: [PATCH] i2c: qcom-geni: Keep comment why interrupts start disabled
Date: Mon, 16 Sep 2024 14:15:17 +0200	[thread overview]
Message-ID: <20240916121516.3102-2-wsa+renesas@sang-engineering.com> (raw)

The to-be-fixed commit rightfully reduced a race window, but also
removed a comment which is still helpful after the fix. Bring the
comment back.

Fixes: e2c85d85a05f ("i2c: qcom-geni: Use IRQF_NO_AUTOEN flag in request_irq()")
