Subject[PATCH 1/2] genirq: allow irq_set_chip_handler_name_locked() to take a const irq_chip
Date
Similar to commit 393e1280f765 ("genirq: Allow irq_chip registration
functions to take a const irq_chip"), allow the
irq_set_chip_handler_name_locked() function to take a const irq_chip
argument.

Given this is the correct approach, can this go through the pinctrl tree?
Of not, do we need an immutable tag?
