When CONFIG_VIDEO_ATOMISP_ISP2401 is not set, sparse shows the following warnings: drivers/staging/media/atomisp/pci/runtime/isys/src/ibuf_ctrl_rmgr.c:34:6: warning: symbol 'ia_css_isys_ibuf_rmgr_init' was not declared. Should it be static? drivers/staging/media/atomisp/pci/runtime/isys/src/ibuf_ctrl_rmgr.c:40:6: warning: symbol 'ia_css_isys_ibuf_rmgr_uninit' was not declared. Should it be static? drivers/staging/media/atomisp/pci/runtime/isys/src/ibuf_ctrl_rmgr.c:46:6: warning: symbol 'ia_css_isys_ibuf_rmgr_acquire' was not declared. Should it be static? drivers/staging/media/atomisp/pci/runtime/isys/src/ibuf_ctrl_rmgr.c:106:6: warning: symbol 'ia_css_isys_ibuf_rmgr_release' was not declared. Should it be static? The symbols stated as not declared are actually declared under ISP2401 definition in ia_css_isys.h. So, the file ibuf_ctrl_rmgr.c should be compiled only when ISP2401 is enabled.
