Running make with defconfig-ath9k produces .config that does not actually build ATH9K. This is observed on 3.13.2-1 and also development retrieved 2014-02-25. The previous stable version 3.12.8-1 does actually build ATH9K. Something happened between 3.12.8-1 and 3.13.2-1 that is preventing ATH9K from being built properly. See the difference in resulting .config files after running "make defconfig-ath9k" in these two versions of stable releases: grep ATH backports-3.13.2-1/.config CPTCFG_ATH_CARDS=m # CPTCFG_ATH_DEBUG is not set # CPTCFG_ATH6KL is not set grep ATH backports-3.12.8-1/.config CPTCFG_ATH_COMMON=m CPTCFG_ATH_CARDS=m # CPTCFG_ATH_DEBUG is not set CPTCFG_ATH9K_HW=m CPTCFG_ATH9K_COMMON=m CPTCFG_ATH9K_BTCOEX_SUPPORT=y CPTCFG_ATH9K=m # CPTCFG_ATH9K_AHB is not set # CPTCFG_ATH9K_LEGACY_RATE_CONTROL is not set CPTCFG_ATH9K_HTC=m # CPTCFG_ATH9K_HTC_DEBUGFS is not set # CPTCFG_ATH6KL is not set # CPTCFG_ATH10K is not set -- To unsubscribe from this list: send the line "unsubscribe backports" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
