Message-Id: <20250407-gpio-regmap-ngpios-v1-1-5ea63fcbde39@linaro.org> Date: Mon, 07 Apr 2025 09:06:15 +0200 From: Bartosz Golaszewski <brgl@...ev.pl> To: Linus Walleij <linus.walleij@...aro.org>, Bartosz Golaszewski <brgl@...ev.pl> Cc: linux-gpio@...r.kernel.org, linux-kernel@...r.kernel.org, Bartosz Golaszewski <bartosz.golaszewski@...aro.org> Subject: [PATCH] gpio: ds4520: don't check the 'ngpios' property in the driver From: Bartosz Golaszewski <bartosz.golaszewski@...aro.org> 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.
