From df1540f8f311a8b2ef0e450e7e40710784acc8c7 Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Tue, 8 Apr 2025 10:40:57 +0200 Subject: [PATCH] gpio: ds4520: don't check the 'ngpios' property in the driver This is already done by the gpio-regmap abstraction by calling gpiochip_get_ngpios(). We don't need to do this at the driver level.
