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

[Marijn Suijten]

Much like 807efb7102e8 ("thermal: qcom-spmi-adc-tm5: suppress
probe-deferral error message") the ADC5 driver also spams a similar
probe-deferral error on startup when a channel is not yet available:

    [    0.343136] qcom-spmi-adc-tm5 1c40000.spmi:pmic@0:adc-tm@3500: get dt data failed: -517

Suppress it by using dev_err_probe instead, which also takes care of
storing the message as reason for deferring.

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.

Fixed up whilst applying.

Applied to the togreg branch of iio.git, but only pushed out as testing for
now as I want to rebase the branch on rc1 once available.
