However, this causes problems with other drivers, in particular an input driver that depends on MFD_INTEL_LPSS_PCI (to be added in a separate commit): drivers/clk/Kconfig:9:error: recursive dependency detected! drivers/clk/Kconfig:9: symbol COMMON_CLK is selected by MFD_INTEL_LPSS drivers/mfd/Kconfig:566: symbol MFD_INTEL_LPSS is selected by MFD_INTEL_LPSS_PCI drivers/mfd/Kconfig:580: symbol MFD_INTEL_LPSS_PCI is implied by KEYBOARD_APPLESPI drivers/input/keyboard/Kconfig:73: symbol KEYBOARD_APPLESPI depends on INPUT drivers/input/Kconfig:8: symbol INPUT is selected by DRM_SIL_SII8620 drivers/gpu/drm/bridge/Kconfig:83: symbol DRM_SIL_SII8620 depends on DRM_BRIDGE drivers/gpu/drm/bridge/Kconfig:1: symbol DRM_BRIDGE is selected by DRM_PL111 drivers/gpu/drm/pl111/Kconfig:1: symbol DRM_PL111 depends on COMMON_CLK According to the docs and general consensus, select should only be used for non user-visible symbols, but both RC_CORE and INPUT are user-visible. Furthermore almost all other references to INPUT throughout the kernel config are depends, not selects. For this reason the first part of this change reverts commit d6abe6df706c. In order to address the original reason for commit d6abe6df706c, namely that not all boards use the remote controller functionality and hence should not need have to deal with RC_CORE, the second part of this change now makes the remote control support in the driver optional and contingent on RC_CORE being defined. And with this the hard dependency on INPUT also goes away as that is only needed if RC_CORE is defined (which in turn already depends on INPUT).
