From: Arnd Bergmann <arnd@xxxxxxxx> The only reference to mtk8195_jpegenc_drvdata is inside of an #ifdef: drivers/media/platform/mediatek/jpeg/mtk_jpeg_core.c:1879:32: error: 'mtk8195_jpegenc_drvdata' defined but not used [-Werror=unused-variable] 1879 | static struct mtk_jpeg_variant mtk8195_jpegenc_drvdata = { | ^~~~~~~~~~~~~~~~~~~~~~~ Fix this by just removing the #ifdef and the corresponding of_match_ptr(). They don't actually serve any purpose here since the driver is only usable when CONFIG_OF is enabled, and build testing without that is not a problem.
