Subject: [PATCH v2 11/13] PCI: apple: Use gpiod_set_value_cansleep in probe flow
Date: Tue, 25 Mar 2025 10:26:08 +0000	[thread overview]
Message-ID: <20250325102610.2073863-12-maz@kernel.org> (raw)
In-Reply-To: <20250325102610.2073863-1-maz@kernel.org>

From: Hector Martin <marcan@marcan.st>

We're allowed to sleep here, so tell the GPIO core by using
gpiod_set_value_cansleep instead of gpiod_set_value.

Fixes: 1e33888fbe44 ("PCI: apple: Add initial hardware bring-up")
