If anyone has any objections, please let me know. ------------------ From: Marc Zyngier [ Upstream commit 704f08753b6dcd0e08c1953af0b2c7f3fac87111 ] The GPIO subsystem has a couple of internal helpers to manage resources on behalf of the irqchip. Expose them so that GPIO drivers can use them directly.
