From 9f69d05b5a85c417c73fa2d5c7a2d507ac81cf4b Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Fri, 24 Jul 2026 16:00:15 -0700 Subject: [PATCH] nfc: st95hf: switch to using sleeping variants of gpiod API The driver does not use gpiod API calls in an atomic context. Switch to gpiod_set_value_cansleep() calls to allow using the driver with GPIO controllers that might need process context to operate.
