Subject: [PATCH v2 5/6] spi: rockchip: Move to pm_runtime_resume_and_get
Date: Fri, 13 Nov 2026 14:50:16 +0100	[thread overview]
Message-ID: <20261113135017.1047959-6-heiko@sntech.de> (raw)
In-Reply-To: <20261113135017.1047959-1-heiko@sntech.de>

From: Heiko Stuebner <heiko.stuebner@cherry.de>

Currently pm_runtime_get_sync() is used, which increments the usage
count even if the resume was not successful.

Move to the more modern pm_runtime_resume_and_get() which handles the
usage counter better.
