Commit 422f10adc3eb ("ASoC: wm8960: Add support for the power supplies") added regulator support to the wm8960 driver, but neglected to update error handling in the probe function. This results in warning backtraces if the probe function fails.

Please think hard before including complete backtraces in upstream reports, they are very large and contain almost no useful information relative to their size so often obscure the relevant content in your message. If part of the backtrace is usefully illustrative (it often is for search engines if nothing else) then it's usually better to pull out the relevant sections.
