[PATCH] drm/radeon: move prototypes to header

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

Global functions in radeon_atpx_handler.c are not declared in a header
but instead in each file using them. This risks the types getting out
of sync and causes warnings:

drivers/gpu/drm/radeon/radeon_atpx_handler.c:64:6: error: no previous prototype for 'radeon_has_atpx' [-Werror=missing-prototypes]
drivers/gpu/drm/radeon/radeon_atpx_handler.c:68:6: error: no previous prototype for 'radeon_has_atpx_dgpu_power_cntl' [-Werror=missing-prototypes]
drivers/gpu/drm/radeon/radeon_atpx_handler.c:72:6: error: no previous prototype for 'radeon_is_atpx_hybrid' [-Werror=missing-prototypes]
drivers/gpu/drm/radeon/radeon_atpx_handler.c:76:6: error: no previous prototype for 'radeon_atpx_dgpu_req_power_for_displays' [-Werror=missing-prototypes]
drivers/gpu/drm/radeon/radeon_atpx_handler.c:594:6: error: no previous prototype for 'radeon_register_atpx_handler' [-Werror=missing-prototypes]
drivers/gpu/drm/radeon/radeon_atpx_handler.c:612:6: error: no previous prototype for 'radeon_unregister_atpx_handler' [-Werror=missing-prototypes]
