Subject: [PATCH 1/1] pinctrl: stmfx: fix null pointer on remove
Date: Fri, 4 Oct 2019 14:23:42 +0200 [thread overview]
Message-ID: <20191004122342.22018-1-amelie.delaunay@st.com> (raw)
dev_get_platdata(&pdev->dev) returns a pointer on struct stmfx_pinctrl,
not on struct stmfx (platform_set_drvdata(pdev, pctl); in probe).
Pointer on struct stmfx is stored in driver data of pdev parent (in probe:
struct stmfx *stmfx = dev_get_drvdata(pdev->dev.parent);).
Fixes: 1490d9f841b1 ("pinctrl: Add STMFX GPIO expander Pinctrl/GPIO driver")
