Subject: [PATCH] i2c: cpm: Use platform_get_irq() to retrieve interrupt

From: Rosen Penev <[email-masked]>
Date: Tue, 2 Jun 2026 17:54:55 -0700

Replace irq_of_parse_and_map() with platform_get_irq() as recommended
for device-managed IRQ lookup. Properly propagate any errors returned
from platform_get_irq(). irq_of_parse_and_map() requires
ire_dispose_mapping(), which is missing.
