Subject: [PATCH] mmc: sdhci-pci-gli: Fix no irq handler from suspend
Date: Mon, 27 Apr 2020 18:30:48 +0800 [thread overview]
Message-ID: <20200427103048.20785-1-benchuanggli@gmail.com> (raw)
From: Ben Chuang <ben.chuang@genesyslogic.com.tw>
The kernel prints a message similar to
"[ 28.881959] do_IRQ: 5.36 No irq handler for vector"
when GL975x resumes from suspend. Implement a resume callback to fix this.
Fixes: 31e43f31890c ("mmc: sdhci-pci-gli: Enable MSI interrupt for GL975x")
