5.4.102 backported a lot of stuff that our WireGuard backport already did, in addition to other patches we had, so those patches were removed from that part of the series. In the process other patches were refreshed or reworked to account for upstream changes. This commit involved `update_kernel.sh -v -u 5.4`.

Subject: [PATCH] wireguard: avoid double unlikely() notation when using
|
|
IS_ERR()
|
|
|
|
commit 30ac4e2f54ec067b7b9ca0db27e75681581378d6 upstream.
|
|
|
|
The definition of IS_ERR() already applies the unlikely() notation
|
|
when checking the error status of the passed pointer. For this
|
|
reason there is no need to have the same notation outside of
|
|
IS_ERR() itself.
|
|
|
|
Clean up code by removing redundant notation.
