The patch for that is simple. Patch enclosed. Please notice that, now with W=1, several new warnings will popup. I'll let to the others to touch there, as I don't have any clue about what's there under omapfb. Those are the new warnings: drivers/video/fbdev/omap2/omapfb/omapfb-main.c: In function ‘omapfb_setup_overlay’: drivers/video/fbdev/omap2/omapfb/omapfb-main.c:891:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (ofbi->rotation_type == OMAP_DSS_ROT_VRFB) { ^ drivers/video/fbdev/omap2/omapfb/omapfb-main.c:896:2: note: here default: ^~~~~~~ drivers/video/fbdev/omap2/omapfb/displays/encoder-tpd12s015.c: In function ‘tpd_probe’: drivers/video/fbdev/omap2/omapfb/displays/encoder-tpd12s015.c:221:26: warning: variable ‘in’ set but not used [-Wunused-but-set-variable] struct omap_dss_device *in, *dssdev; ^~ drivers/video/fbdev/omap2/omapfb/dss/dispc.c: In function ‘calc_vrfb_rotation_offset’: drivers/video/fbdev/omap2/omapfb/dss/dispc.c:1905:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (color_mode == OMAP_DSS_COLOR_YUV2 || ^ drivers/video/fbdev/omap2/omapfb/dss/dispc.c:1908:2: note: here case OMAP_DSS_ROT_90: ^~~~ drivers/video/fbdev/omap2/omapfb/dss/dispc.c:1927:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (color_mode == OMAP_DSS_COLOR_YUV2 || ^ drivers/video/fbdev/omap2/omapfb/dss/dispc.c:1930:2: note: here case OMAP_DSS_ROT_90 + 4: ^~~~ drivers/video/fbdev/omap2/omapfb/dss/venc.c:223:33: warning: ‘venc_config_pal_bdghi’ defined but not used [-Wunused-const-variable=] static const struct venc_config venc_config_pal_bdghi = { ^~~~~~~~~~~~~~~~~~~~~ drivers/video/fbdev/omap2/omapfb/dss/dsi.c: In function ‘_dsi_print_reset_status’: drivers/video/fbdev/omap2/omapfb/dss/dsi.c:1189:6: warning: variable ‘l’ set but not used [-Wunused-but-set-variable] u32 l; ^ drivers/video/fbdev/omap2/omapfb/dss/dsi.c: In function ‘dsi_proto_timings’: drivers/video/fbdev/omap2/omapfb/dss/dsi.c:3638:42: warning: variable ‘tclk_trail’ set but not used [-Wunused-but-set-variable] unsigned tlpx, tclk_zero, tclk_prepare, tclk_trail; ^~~~~~~~~~ drivers/video/fbdev/omap2/omapfb/dss/dsi.c: In function ‘dsi_update’: drivers/video/fbdev/omap2/omapfb/dss/dsi.c:4051:10: warning: variable ‘dh’ set but not used [-Wunused-but-set-variable] u16 dw, dh; ^~ drivers/video/fbdev/omap2/omapfb/dss/dsi.c:4051:6: warning: variable ‘dw’ set but not used [-Wunused-but-set-variable] u16 dw, dh; ^~ drivers/video/fbdev/omap2/omapfb/dss/hdmi4_core.c: In function ‘hdmi4_audio_config’: drivers/video/fbdev/omap2/omapfb/dss/hdmi4_core.c:693:6: warning: variable ‘err’ set but not used [-Wunused-but-set-variable] int err, n, cts, channel_count; ^~~ drivers/video/fbdev/omap2/omapfb/dss/hdmi5_core.c: In function ‘hdmi5_audio_config’: drivers/video/fbdev/omap2/omapfb/dss/hdmi5_core.c:804:6: warning: variable ‘err’ set but not used [-Wunused-but-set-variable] int err, n, cts, channel_count; ^~~ Thanks, Mauro --- [PATCH] omap2: omapfb: allow building it with COMPILE_TEST This driver builds cleanly with COMPILE_TEST, and it is needed in order to allow building drivers/media omap2 driver. So, change the logic there to allow building it.
