If anyone has any objections, please let me know. ------------------ From: Alexander Stein commit cc9432c4fb159a3913e0ce3173b8218cd5bad2e0 upstream. This change uses the appropriate _cansleep or non-sleeping API for reading GPIO read-only state. This allows users with GPIOs that never sleepbeing called in atomic context. Implement the same mechanism as in commit 52af318c93e97 ("mmc: Allow non-sleeping GPIO cd").
