+Subject: mmc: core: properly select voltage range without power cycle
+
+From: Yann Gautier <yann.gautier@foss.st.com>
+
+commit 39a72dbfe188291b156dd6523511e3d5761ce775 upstream.
+
+In mmc_select_voltage(), if there is no full power cycle, the voltage
+range selected at the end of the function will be on a single range
+(e.g. 3.3V/3.4V). To keep a range around the selected voltage (3.2V/3.4V),
+the mask shift should be reduced by 1.
+
+This issue was triggered by using a specific SD-card (Verbatim Premium
+16GB UHS-1) on an STM32MP157C-DK2 board. This board cannot do UHS modes
+and there is no power cycle. And the card was failing to switch to
+high-speed mode. When adding the range 3.2V/3.3V for this card with the
+proposed shift change, the card can switch to high-speed mode.
+

+Subject: mmc: sdhci-pci: Fix possible memory leak caused by missing pci_dev_put()
+
+From: Xiongfeng Wang <wangxiongfeng2@huawei.com>
+
+commit 222cfa0118aa68687ace74aab8fdf77ce8fbd7e6 upstream.
+
+pci_get_device() will increase the reference count for the returned
+pci_dev. We need to use pci_dev_put() to decrease the reference count
+before amd_probe() returns. There is no problem for the 'smbus_dev ==
+NULL' branch because pci_dev_put() can also handle the NULL input
+parameter case.
