It's not clear what was the intention of redundant usage of IS_ERR() around the clock pointer since with the error check of devm_clk_get() followed by bailout it can't be invalid, Simplify the code which fetches the input clock by using devm_clk_get_optional(). It will allow to switch to device properties approach in the future. Link: https://lore.kernel.org/all/20211206165542.69887-1-andriy.shevchenko@linux.intel.comSigned-off-by:

Allwinner R40 (also known as A40i, T3, V40) has a CAN controller. The controller is the same as in earlier A10 and A20 SoCs, but needs reset line to be deasserted before use. This patch adds a CAN node and the corresponding pinctrl descriptions. Link: https://lore.kernel.org/all/20211122104616.537156-4-boger@wirenboard.comSigned-off-by:

In [1], we introduced a set of units in linux/can/bittiming.h. Since then, generic SI prefixes were added to linux/units.h in [2]. Those new prefixes can perfectly replace CAN specific ones. This patch replaces all occurrences of the CAN units with their corresponding prefix (from linux/units) and the unit (as a comment) according to below table. CAN units SI metric prefix (from linux/units) + unit (as a comment) ------------------------------------------------------------------------ CAN_KBPS KILO /* BPS */ CAN_MBPS MEGA /* BPS */ CAM_MHZ MEGA /* Hz */ The definition are then removed from linux/can/bittiming.h [1] commit 1d775076 ("can: bittiming: add CAN_KBPS, CAN_MBPS and CAN_MHZ macros") [2] commit 26471d4a ("units: Add SI metric prefix definitions") Link: https://lore.kernel.org/all/20211124014536.782550-1-mailhol.vincent@wanadoo.frSuggested-by:

Now that the OSN code is gone, we don't need the second switch statement in the RX path. And getting rid of its (unreachable) default case is a nice simplification. Also don't pass in the full HW header, all we still need is a flag to indicate whether the skb can use CSO. This we can already obtain during the first peek at the HW header. Signed-off-by:

When building under -Warray-bounds, the compiler is especially conservative when faced with casts from a smaller object to a larger object. While this has found many real bugs, there are some cases that are currently false positives (like here). With this as one of the last few instances of the warning in the kernel before -Warray-bounds can be enabled globally, rearrange the functions so that there is a header-only version of hvs_send_data(). Silences this warning: net/vmw_vsock/hyperv_transport.c: In function 'hvs_shutdown_lock_held.constprop': net/vmw_vsock/hyperv_transport.c:231:32: warning: array subscript 'struct hvs_send_buf[0]' is partly outside array bounds of 'struct vmpipe_proto_header[1]' [-Warray-bounds] 231 | send_buf->hdr.pkt_type = 1; | ~~~~~~~~~~~~~~~~~~~~~~~^~~ net/vmw_vsock/hyperv_transport.c:465:36: note: while referencing 'hdr' 465 | struct vmpipe_proto_header hdr; | ^~~ This change results in no executable instruction differences.

Mat Martineau says: ==================== mptcp: New features for MPTCP sockets and netlink PM This collection of patches adds MPTCP socket support for a few socket options, ioctls, and one ancillary data type (specifics for each are listed below). There's also a patch modifying the netlink MPTCP path manager API to allow setting the backup flag on a configured interface using the endpoint ID instead of the full IP address. Patches 1 & 2: TCP_INQ cmsg and selftests. Patches 2 & 3: SIOCINQ, OUTQ, and OUTQNSD ioctls and selftests. Patch 5: Change backup flag using endpoint ID. Patches 6 & 7: IP_TOS socket option and selftests. Patches 8-10: TCP_CORK and TCP_NODELAY socket options. Includes a tcp change to expose __tcp_sock_set_cork() and __tcp_sock_set_nodelay() for use by MPTCP. ==================== Link: https://lore.kernel.org/r/20211203223541.69364-1-mathew.j.martineau@linux.intel.comSigned-off-by:

First, add cork and nodelay fields to the mptcp_sock structure so they can be used in sync_socket_options(), and fill them on setsockopt while holding the msk socket lock. Then, on setsockopt set proper tcp_sk(ssk)->nonagle values for subflows by calling __tcp_sock_set_cork() or __tcp_sock_set_nodelay() on the ssk while holding the ssk socket lock. tcp_push_pending_frames() will be invoked on the ssk if a cork was cleared or nodelay was set. Also set MPTCP_PUSH_PENDING bit by calling mptcp_check_and_set_pending(). This will lead to __mptcp_push_pending() being called inside mptcp_release_cb() with new tcp_sk(ssk)->nonagle. Also add getsockopt support for TCP_CORK and TCP_NODELAY. Acked-by:
