Subject: [PATCH 7/9] mmc: sdhci: Do not unnecessarily enable wakeup for SDIO card interrupt
Date: Wed, 20 Dec 2017 10:18:51 +0200 [thread overview]
Message-ID: <1513757933-11232-8-git-send-email-adrian.hunter@intel.com> (raw)
In-Reply-To: <1513757933-11232-1-git-send-email-adrian.hunter@intel.com>
Do not enable wakeup for SDIO card interrupt unless the SDIO function
driver has requested it which is indicated by mmc_card_wake_sdio_irq().
