[PATCH AUTOSEL 4.14 122/371] mmc: sdhci-brcmstb: handle mmc_of_parse() errors during probe

[Sasha Levin]

From: Stefan Wahren <stefan.wahren@i2se.com>

[ Upstream commit 1e20186e706da8446f9435f2924cd65ab1397e73 ]

We need to handle mmc_of_parse() errors during probe otherwise the
MMC driver could start without proper initialization (e.g. power sequence).

[PATCH AUTOSEL 4.14 187/371] mmc: core: fix possible use after free of host

[Sasha Levin]

From: Pan Bian <bianpan2016@163.com>

[ Upstream commit 8e1943af2986db42bee2b8dddf49a36cdb2e9219 ]

In the function mmc_alloc_host, the function put_device is called to
release allocated resources when mmc_gpio_alloc fails. Finally, the
function pointed by host->class_dev.class->dev_release (i.e.,
mmc_host_classdev_release) is used to release resources including the
host structure. However, after put_device, host is used and released
again. Resulting in a use-after-free bug.

[PATCH AUTOSEL 4.14 353/371] mmc: sdio: fix wl1251 vendor id

[Sasha Levin]

From: "H. Nikolaus Schaller" <hns@goldelico.com>

[ Upstream commit e5db673e7fe2f971ec82039a28dc0811c2100e87 ]

v4.11-rc1 did introduce a patch series that rearranged the
sdio quirks into a header file. Unfortunately this did forget
to handle SDIO_VENDOR_ID_TI differently between wl1251 and
wl1271 with the result that although the wl1251 was found on
the sdio bus, the firmware did not load any more and there was
no interface registration.

This patch defines separate constants to be used by sdio quirks
and drivers.

[PATCH AUTOSEL 4.14 354/371] mmc: core: fix wl1251 sdio quirks

[Sasha Levin]

From: "H. Nikolaus Schaller" <hns@goldelico.com>

[ Upstream commit 16568b4a4f0c34bd35cfadac63303c7af7812764 ]

wl1251 and wl1271 have different vendor id and device id.
So we need to handle both with sdio quirks.
