+Subject: mmc: core: Prevent processing SDIO IRQs when the card is suspended
+
+From: Ulf Hansson <ulf.hansson@linaro.org>
+
+commit 83293386bc95cf5e9f0c0175794455835bd1cb4a upstream.
+
+Processing of SDIO IRQs must obviously be prevented while the card is
+system suspended, otherwise we may end up trying to communicate with an
+uninitialized SDIO card.
+
+Reports throughout the years shows that this is not only a theoretical
+problem, but a real issue. So, let's finally fix this problem, by keeping
+track of the state for the card and bail out before processing the SDIO
+IRQ, in case the card is suspended.

+Subject: scsi: ufs: Avoid runtime suspend possibly being blocked forever
+
+From: Stanley Chu <stanley.chu@mediatek.com>
+
+commit 24e2e7a19f7e4b83d0d5189040d997bce3596473 upstream.
+
+UFS runtime suspend can be triggered after pm_runtime_enable() is invoked
+in ufshcd_pltfrm_init(). However if the first runtime suspend is triggered
+before binding ufs_hba structure to ufs device structure via
+platform_set_drvdata(), then UFS runtime suspend will be no longer
+triggered in the future because its dev->power.runtime_error was set in the
+first triggering and does not have any chance to be cleared.
+
+To be more clear, dev->power.runtime_error is set if hba is NULL in
+ufshcd_runtime_suspend() which returns -EINVAL to rpm_callback() where
+dev->power.runtime_error is set as -EINVAL. In this case, any future
+rpm_suspend() for UFS device fails because rpm_check_suspend_allowed()
+fails due to non-zero
+dev->power.runtime_error.
+
+To resolve this issue, make sure the first UFS runtime suspend get valid
+"hba" in ufshcd_runtime_suspend(): Enable UFS runtime PM only after hba is
+successfully bound to UFS device structure.
+
+Fixes: 62694735ca95 ([SCSI] ufs: Add runtime PM support for UFS host controller driver)

+Subject: usb: chipidea: udc: workaround for endpoint conflict issue
+
+From: Peter Chen <peter.chen@nxp.com>
+
+commit c19dffc0a9511a7d7493ec21019aefd97e9a111b upstream.
+
+An endpoint conflict occurs when the USB is working in device mode
+during an isochronous communication. When the endpointA IN direction
+is an isochronous IN endpoint, and the host sends an IN token to
+endpointA on another device, then the OUT transaction may be missed
+regardless the OUT endpoint number. Generally, this occurs when the
+device is connected to the host through a hub and other devices are
+connected to the same hub.
+
+The affected OUT endpoint can be either control, bulk, isochronous, or
+an interrupt endpoint. After the OUT endpoint is primed, if an IN token
+to the same endpoint number on another device is received, then the OUT
+endpoint may be unprimed (cannot be detected by software), which causes
+this endpoint to no longer respond to the host OUT token, and thus, no
+corresponding interrupt occurs.
+
+There is no good workaround for this issue, the only thing the software
+could do is numbering isochronous IN from the highest endpoint since we
+have observed most of device number endpoint from the lowest.
