Subject: iio: adc: twl4030: Return an error if we can not enable the vusb3v1 regulator in... 
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=53063846affd27def6f96e13a9fb80b9a3c2d126;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

iio: adc: twl4030: Return an error if we can not enable the vusb3v1 regulator in 'twl4030_madc_probe()'

If we can not enable the regulator, go through the error handling path
instead of silently continuing.
