Re: [PATCH] thermal: qcom-spmi-adc5: Suppress probe-deferral error message

[Marijn Suijten]

Whoops, that tile must of course have started with:

    iio: adc: qcom-spmi-adc5:

instead of blindly copying the suffix from the thermal monitor patch
(this driver is not a thermal monitor...).  I'll send a v2 if there are
no other objections, unless this can be fixed up when the patch is
applied.

Apologies for the clumsiness.
