".ht_cap = WL12xx_HT_CAP" in wl1271_main.c adds only on patch 03/04. I believe that adding "#ifdef CONFIG_WL1271_HT" in wl1271_main.c with early patch on code that not exist is less clear. Squashing the patches 03 and 04 to one in v2 could prevent that but it will not emphasize the configuration option. Is there are cases that the some patches from series not applies? Bisection (which seems to be my watch word, at the moment) could jump into the middle of random patch sets like this. Personally, I'd squash 3 and 4 into one patch: I.e. you're saying "here's the functionality and it's protected by a Kconfig variable." The fact that it's touching the Kconfig file is probably enough emphasis in and of itself. > Thanks for your review, No problem, -- Julian Calaby Email: julian.calaby@gmail.com Profile: http://www.google.com/profiles/julian.calaby/ .Plan: http://sites.google.com/site/juliancalaby/
