[PATCH AUTOSEL 4.19 04/37] pinctrl: meson-gxl: fix GPIOX sdio pins

[Sasha Levin]

From: Nicolas Belin <nbelin@baylibre.com>

[ Upstream commit dc7a06b0dbbafac8623c2b7657e61362f2f479a7 ]

In the gxl driver, the sdio cmd and clk pins are inverted. It has not caused
any issue so far because devices using these pins always take both pins
so the resulting configuration is OK.

[PATCH AUTOSEL 4.19 06/37] pinctrl: core: Remove extra kref_get which blocks hogs being freed

[Sasha Levin]

From: Charles Keepax <ckeepax@opensource.cirrus.com>

[ Upstream commit aafd56fc79041bf36f97712d4b35208cbe07db90 ]

kref_init starts with the reference count at 1, which will be balanced
by the pinctrl_put in pinctrl_unregister. The additional kref_get in
pinctrl_claim_hogs will increase this count to 2 and cause the hogs to
not get freed when pinctrl_unregister is called.
