Subject: regulator: keep index within bounds in da9034_get_ldo12_voltage()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=495353a3f7fbb11e5100c9258365ff65a4834b37;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

regulator: keep index within bounds in da9034_get_ldo12_voltage()

If selector equals ARRAY_SIZE(da9034_ldo12_data), that is one too
large already.
