licensing: add spdx to our .cocci files Since those are chunks of code based on our codebase, it's easiest to use the same license. 2021-10-01 12:28:36 +02:00			`/* SPDX-License-Identifier: LGPL-2.1-or-later */`

tree-wide: use -EBADF for fd initialization -1 was used everywhere, but -EBADF or -EBADFD started being used in various places. Let's make things consistent in the new style. Note that there are two candidates: EBADF 9 Bad file descriptor EBADFD 77 File descriptor in bad state Since we're initializating the fd, we're just assigning a value that means "no fd yet", so it's just a bad file descriptor, and the first errno fits better. If instead we had a valid file descriptor that became invalid because of some operation or state change, the other errno would fit better. In some places, initialization is dropped if unnecessary. 2022-12-19 13:07:42 +01:00			`- fd = -EBADF;`
