Subject: [PATCH 1/4] mmc: rtsx_usb_sdmmc: Fix error-path in sd_set_power_mode()
Date: Tue, 10 Jun 2025 13:16:23 +0200	[thread overview]
Message-ID: <20250610111633.504366-2-ulf.hansson@linaro.org> (raw)
In-Reply-To: <20250610111633.504366-1-ulf.hansson@linaro.org>

In the error path of sd_set_power_mode() we don't update host->power_mode,
which could lead to an imbalance of the runtime PM usage count. Fix this by
always updating host->power_mode.
