From 72b38caf7b7568ebc167fdd4ec5fa1daa113d08b Mon Sep 17 00:00:00 2001 From: Baruch Siach Date: Thu, 21 Jun 2018 16:38:46 +0300 Subject: [PATCH] gpio: pca953x: suppress interrupts warning when not applicable Don't warn about missing interrupts support when the parent interrupt is not defined. Enabling interrupts support would not make it work anyway.
