From 8a18b9733239f794cb5e53c876760302a21f804d Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Wed, 14 Feb 2024 10:31:39 +0100 Subject: [PATCH] pwm: iqs620a: Create a wrapper for converting a pwm_chip to driver data MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit There is no semantic change. The new function just implements what was open-coded twice in the driver before.
