--------------------------------

[ Upstream commit 3fa9e4cf ]

If devm_of_platform_populate() fails, some resources need to be
released.

Introduce a mx25_tsadc_unset_irq() function that undoes
mx25_tsadc_setup_irq() and call it both from the new error handling path
of the probe and in the remove function.
