From 6db9cdfdc3c558e50c7ca8a992396585843bf962 Mon Sep 17 00:00:00 2001 From: Wenhua Lin Date: Thu, 21 Sep 2023 20:25:27 +0800 Subject: [PATCH] gpio: pmic-eic-sprd: Add can_sleep flag for PMIC EIC chip [ Upstream commit 26d9e5640d2130ee16df7b1fb6a908f460ab004c ] The drivers uses a mutex and I2C bus access in its PMIC EIC chip get implementation. This means these functions can sleep and the PMIC EIC chip should set the can_sleep property to true. This will ensure that a warning is printed when trying to get the value from a context that potentially can't sleep.
