Hello Tomi Valkeinen, The patch f5bab2229190: "OMAPDSS: HDMI: Add OMAP5 HDMI support" from Mar 13, 2014, leads to the following static checker warning: drivers/video/fbdev/omap2/dss/hdmi5_core.c:719 hdmi5_core_audio_config() warn: '(3) - (4)' negative one Uh... This is really weird, I have no idea what this warning is or why it's triggered. I've even looked at the code which triggers it but that has no documentation. :P Still it seems like something worth looking into. drivers/video/fbdev/omap2/dss/hdmi5_core.c 713 /* PCM audio mode */ 714 val = (cfg->iec60958_cfg->status[0] & IEC958_AES0_CON_MODE) >> 6; 715 REG_FLD_MOD(base, HDMI_CORE_FC_AUDSCHNLS(2), val, 6, 4); 716 717 /* Source number */ 718 val = cfg->iec60958_cfg->status[2] & IEC958_AES2_CON_SOURCE; 719 REG_FLD_MOD(base, HDMI_CORE_FC_AUDSCHNLS(2), val, 3, 4); ^^^^ Aren't these reversed? This seems like an invalid bitfield range. 720 721 /* Channel number right 0 */ 722 REG_FLD_MOD(base, HDMI_CORE_FC_AUDSCHNLS(3), 2, 3, 0); 723 /* Channel number right 1*/ 724 REG_FLD_MOD(base, HDMI_CORE_FC_AUDSCHNLS(3), 4, 7, 4); 725 /* Channel number right 2 */ 726 REG_FLD_MOD(base, HDMI_CORE_FC_AUDSCHNLS(4), 6, 3, 0); 727 /* Channel number right 3*/ 728 REG_FLD_MOD(base, HDMI_CORE_FC_AUDSCHNLS(4), 8, 7, 4); 729 /* Channel number left 0 */ 730 REG_FLD_MOD(base, HDMI_CORE_FC_AUDSCHNLS(5), 1, 3, 0); 731 /* Channel number left 1*/ 732 REG_FLD_MOD(base, HDMI_CORE_FC_AUDSCHNLS(5), 3, 7, 4); 733 /* Channel number left 2 */ 734 REG_FLD_MOD(base, HDMI_CORE_FC_AUDSCHNLS(6), 5, 3, 0); 735 /* Channel number left 3*/ regards, dan carpenter -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
