Add an of_node_put when a tested device node is not available.

2019-02-24net: hns3: fix setting of the hns reset_type for rdma hw errorsShiju Jose
Presently the hns reset_type for the roce errors is set in the hclge_log_and_clear_rocee_ras_error function. This function is also called to detect and clear roce errors while enabling the rdma error interrupts. However there is no hns reset requested for this case. This can cause issue of wrong reset_type used with subsequent hns reset as the reset_type set in the above case was not cleared. This patch moves setting of hns reset_type for the roce errors from hclge_log_and_clear_rocee_ras_error function to hclge_handle_rocee_ras_error.

2019-02-24mlxsw: spectrum_acl: Enable vregion rehash per-profileJiri Pirko
For MR ACL profile is does not make sense to do periodical rehashes, as there is only one mask in use during the whole vregion lifetime. Therefore periodical work is scheduled but the rehash never happens. So allow to enable/disable rehash for the whole group, which is added per-profile. Disable rehashing for MR profile. Addition to the vregion list is done only in case the rehash is enable on the particular vregion. Also, the addition is moved after delayed work init to avoid schedule of uninitialized work from vregion_rehash_intrvl_set(). Symmetrically, deletion from the list is done before canceling the delayed work so it is not scheduled by vregion_rehash_intrvl_set() again.

2019-02-24net: phy: check PMAPMD link status only in genphy_c45_read_linkHeiner Kallweit
The current code reports a link as up if all devices (except a few blacklisted ones) report the link as up. This breaks Aquantia AQCS109 for lower speeds because on this PHY the PCS link status reflects a 10G link only. For Marvell there's a similar issue, therefore PHYXS device isn't checked. There may be more PHYs where depending on the mode the link status of only selected devices is relevant. For now it seems to be sufficient to check the link status of the PMAPMD device only. Leave the loop in the code to be prepared in case we have to add functionality to check more than one device, depending on the mode. Successfully tested on a board with an AQCS109.

2019-02-24ACPICA: ACPI 6.3: add PCC operation region support for AML interpreterErik Schmauss
ACPICA commit a4849944e80f97970e99843f4975850753584a4e This change adds PCC operation region support in the AML interpreter and a default handler for acpiexec. According to the specification, the PCC operation region performs a transaction when the COMD field is written. This allows ASL to write data to other fields before sending the data. In order to accommodate this protocol, a temorary buffer is added to the regionfield object to accumulate writes. If any offset that spans COMD is written, the temporary buffer is sent to the PCC operation region handler to be processed. This change also renames the PCC keyword to platform_comm_channel.
