Thanks for your help Greg! I agreed with you. I'm a newbie still learning the kernel code style. When I run: perl scripts/checkpatch.pl -f drivers/staging/wlan-ng/cfg80211.c I get the following warning: CHECK: Unnecessary parentheses around 'wlandev->msdstate != WLAN_MSD_RUNNING' #268: FILE: drivers/staging/wlan-ng/cfg80211.c:268: + if (!wlandev || (wlandev->msdstate != WLAN_MSD_RUNNING)) and that is why I proposed the change. > Please don't make things such that it is harder to read for a > programmer. > Is OK to say that in cases of newline after the || parentheses could be removed without affect code clarity? Would you accept a v3 of this patch that just removes parentheses in those cases? Or you prefer to drop this patch? cheers frank _______________________________________________ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
