From: Arnd Bergmann <arnd@xxxxxxxx> This is one of three drivers that trigger -Wenum-compare-conditional warnings with clang: drivers/net/wireless/realtek/rtw89/core.c:1806:14: error: conditional expression between different enumeration types ('enum nl80211_eht_gi' and 'enum nl80211_he_gi') [-Werror,-Wenum-compare-conditional] 1806 | return eht ? NL80211_RATE_INFO_EHT_GI_0_8 : | ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 1807 | NL80211_RATE_INFO_HE_GI_0_8; | ~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/net/wireless/realtek/rtw89/core.c:1810:14: error: conditional expression between different enumeration types ('enum nl80211_eht_gi' and 'enum nl80211_he_gi') [-Werror,-Wenum-compare-conditional] 1810 | return eht ?

NL80211_RATE_INFO_EHT_GI_3_2 : | ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 1819 | NL80211_RATE_INFO_HE_GI_3_2; | ~~~~~~~~~~~~~~~~~~~~~~~~~~~ In this case, all four warnings can be easily avoided by splitting the function into two separate ones, in a way that helps readability as well, at the expense of a few extra source lines.
