regulator: irq_helpers: duplicate IRQ name
[ Upstream commit 7ab681ddedd4b6dd2b047c74af95221c5f827e1d ]
The regulator IRQ helper requires caller to provide pointer to IRQ name
which is kept in memory by caller. All other data passed to the helper
in the regulator_irq_desc structure is copied. This can cause some
confusion and unnecessary complexity.
Make the regulator_irq_helper() to copy also the provided IRQ name
information so caller can discard the name after the call to
regulator_irq_helper() completes.
