Subject: [PATCH] iio: adc128s052: Fix the error handling path of 'adc128_probe()'
Git-commit: bbcf40816b547b3c37af49168950491d20d81ce1
Patch-mainline: v5.15-rc6
References: git-fixes stable-5.14.14
A successful 'regulator_enable()' call should be balanced by a
corresponding 'regulator_disable()' call in the error handling path of the
probe, as already done in the remove function.
Update the error handling path accordingly.
