Subject: regulator: Ensure val is initialised in 88pm8607 choose_voltage()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ddec68107ab101d9ff934811d5598f5c613027f2;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

regulator: Ensure val is initialised in 88pm8607 choose_voltage()

If we fall through it means that we hit an unknown regulator/chip
combination so set -ENOENT as an explicit flag (the return code
is only used internally).
