Part of my QC process before I send a patch is to search my inbox to see if I have already sent the patch before. I have the memory of a gnat and static checker warnings all look the same after a while so I once wrote the same patch three times before I implemented this as part of my QC process. Anyway, it turns out that I did report this bug already but since you hadn't sent a fix, I decided to just send my fix instead of deleting it. When kbuild detects a bug in your patch then please fix it as soon as you can. Certainly don't wait until "all the TODO items" are done. (0_0) Just do what I do and promise to "fix it tomorrow morning" and then forget about it forever. ;) regards, dan carpenter > On Thu, Feb 25, 2021 at 01:03:03PM +0300, Dan Carpenter wrote: > > tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master > > head: 29c395c77a9a514c5857c45ceae2665e9bd99ac7 > > commit: 953b94009377419f28fd0153f91fcd5b5a347608 staging: qlge: Initialize devlink health dump framework > > config: i386-randconfig-m021-20210225 (attached as .config) > > compiler: gcc-9 (Debian 9.3.0-15) 9.3.0 > > > > If you fix the issue, kindly add following tag as appropriate > > Reported-by: kernel test robot <lkp(a)intel.com&gt;
