Subject: i2c: mux: pinctrl: potential NULL dereference on error
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=be9bac020cacd0cdf758b4a6d847a0ba835475b9;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

i2c: mux: pinctrl: potential NULL dereference on error

If i2c_mux_alloc() fails then we'd have a NULL dereference here.

Fixes: c4aee3e1b0de ("i2c: mux: pinctrl: remove platform_data")
