From 39e4e75a9f1cc4c448e965c14962a62c803922e3 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Tue, 12 Oct 2021 19:38:36 -0700 Subject: [PATCH] Input: tsc200x - make tsc200x_remove() return void MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Up to now tsc200x_remove() returns zero unconditionally. Make it return void instead which makes it easier to see in the callers that there is no error to handle. Also the return value of i2c and spi remove callbacks is ignored anyway.
