From 2778caedb5667239823a29148dfc48b26a8b3c2a Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Sat, 30 Jul 2022 14:48:33 +0200 Subject: [PATCH] soc: mediatek: Let PMIC Wrapper and SCPSYS depend on OF MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit With the following configuration options: CONFIG_OF is not set CONFIG_MTK_PMIC_WRAP=y CONFIG_MTK_SCPSYS=y we get the following build warnings: CC drivers/soc/mediatek/mtk-pmic-wrap.o drivers/soc/mediatek/mtk-pmic-wrap.c:2138:34: warning: ‘of_pwrap_match_tbl’ defined but not used [-Wunused-const-variable=] drivers/soc/mediatek/mtk-pmic-wrap.c:1953:34: warning: ‘of_slave_match_tbl’ defined but not used [-Wunused-const-variable=] CC drivers/soc/mediatek/mtk-scpsys.o drivers/soc/mediatek/mtk-scpsys.c:1084:34: warning: ‘of_scpsys_match_tbl’ defined but not used [-Wunused-const-variable=] Looking at the code, both drivers can only bind to OF-defined device nodes, so these drivers are useless without OF and should therefore depend on it. Also drop of_match_ptr() from both drivers. We already know what it will resolve to, so we might as well save cpp some work. Developers or QA teams who wish to test-build the code can still do so by enabling CONFIG_OF, which is available on all architectures and has no dependencies.
