Pull SPDX updates from Greg KH:
"Here are three SPDX patches for 5.7-rc1.One fixes up the SPDX tag for a single driver, while the other two go
through the tree and add SPDX tags for all of the .gitignore files as
needed.Nothing too complex, but you will get a merge conflict with your
current tree, that should be trivial to handle (one file modified by
two things, one file deleted.)All three of these have been in linux-next for a while, with no

There's a semantic conflict in the Octeon staging network driver, which
used the skb_reset_tc() function to reset skb state when re-using an
skb. But that inline helper function was removed in mainline by commit
2c64605b590e ("net: Fix CONFIG_NET_CLS_ACT=n and
CONFIG_NFT_FWD_NETDEV={y, m} build").Fix it by using skb_reset_redirect() instead. Also move it out of the
This code path only ends up triggering if REUSE_SKBUFFS_WITHOUT_FREE is
enabled, which in turn only happens if you don't have CONFIG_NETFILTER
configured. Which was how this wasn't caught by the usual allmodconfig

Pull staging and IIO driver updates from Greg KH:
"Here is the big staging and IIO driver pull request for 5.7-rc1.We again end up deleting more code than we added here, thanks to
finally getting rid of the old and obsolete wireless USB stuff, and
the exfat code (which is coming in again through the vfs tree in a
much cleaner version).But some code does come back, with the octeon drivers being found to
actually be used in the wild, so those deletions are now reverted.Other than those major things, just loads and loads of tiny checkpatch
cleanups all over the place, along with new IIO drivers and fixes.All have been in linux-next with no reported issues"
