From ea6b13e9fed0fda9532ee04d38ed1bef1edbfdbf Mon Sep 17 00:00:00 2001 From: Fabrizio Castro Date: Mon, 19 Nov 2018 13:26:18 +0000 Subject: [PATCH] drm/bridge/sii902x: Add missing dependency on I2C_MUX kbuild test robot reports: >> ERROR: "i2c_mux_add_adapter" [drivers/gpu/drm/bridge/sii902x.ko] undefined! >> ERROR: "i2c_mux_alloc" [drivers/gpu/drm/bridge/sii902x.ko] undefined! >> ERROR: "i2c_mux_del_adapters" [drivers/gpu/drm/bridge/sii902x.ko] undefined! Quite obviously the driver depends on I2C_MUX, but adding a "depends on" introduces a recursive dependency, therefore this patch selects I2C_MUX instead.
