Subject: [PATCH] net: ieee802154: return -EINVAL for unknown addr type
Git-commit: 30393181fdbc1608cc683b4ee99dcce05ffcc8c7
Patch-mainline: v6.1-rc1
References: git-fixes
This patch adds handling to return -EINVAL for an unknown addr type. The
current behaviour is to return 0 as successful but the size of an
unknown addr type is not defined and should return an error like -EINVAL.
Fixes: 94160108a70c ("net/ieee802154: fix uninit value bug in dgram_sendmsg")
