From 01407940f9cd3bd87f3b707f7175f6f41ac1238b Mon Sep 17 00:00:00 2001 From: William Breathitt Gray Date: Mon, 3 Apr 2023 13:53:13 -0400 Subject: gpio: 104-dio-48e: Enable use_raw_spinlock for dio48e_regmap_config The dio48e regmap can be used in an interrupt context by regmap-irq. To prevent a deadlock, enable use_raw_spinlock for dio48e_regmap_config.
