Subject: [PATCH] rtc: nvidia-vrs10: remove locking in IRQ handler
Date: Fri,  9 Oct 2026 23:23:47 +0200	[thread overview]
Message-ID: <20261009212347.490403-1-alexandre.belloni@bootlin.com> (raw)

From: Alexandre Belloni <alexandre.belloni@bootlin.com>

Remove locking in the interrupt handler as it is not necessary to be locked
while calling rtc_update_irq().
