staging: octeon: Drop on uncorrectable alignment or FCS error

2020-11-05T10:08:55Z

commit 49d28ebdf1e30d806410eefc7de0a7a1ca5d747c upstream. Currently in case of alignment or FCS error if the packet cannot be corrected it's still not dropped. Report the error properly and drop the packet while making the code around a little bit more readable. Fixes: 80ff0fd3ab64 ("Staging: Add octeon-ethernet driver files.")

2020-11-05T10:08:55Z

commit 179f5dc36b0a1aa31538d7d8823deb65c39847b3 upstream. The PHYs must be registered once in device probe function, not in device open callback because it's only possible to register them once.

staging: comedi: cb_pcidas: Allow 2-channel commands for AO subdevice

2020-11-05T10:08:55Z

commit 647a6002cb41d358d9ac5de101a8a6dc74748a59 upstream. The "cb_pcidas" driver supports asynchronous commands on the analog output (AO) subdevice for those boards that have an AO FIFO. The code (in `cb_pcidas_ao_check_chanlist()` and `cb_pcidas_ao_cmd()`) to validate and set up the command supports output to a single channel or to two channels simultaneously (the boards have two AO channels). However, the code in `cb_pcidas_auto_attach()` that initializes the subdevices neglects to initialize the AO subdevice's `len_chanlist` member, leaving it set to 0, but the Comedi core will "correct" it to 1 if the driver neglected to set it. This limits commands to use a single channel (either channel 0 or 1), but the limit should be two channels. Set the AO subdevice's `len_chanlist` member to be the same value as the `n_chan` member, which will be 2.

KVM: arm64: Fix AArch32 handling of DBGD{CCINT,SCRext} and DBGVCR

2020-11-05T10:08:55Z

commit 4a1c2c7f63c52ccb11770b5ae25920a6b79d3548 upstream. The DBGD{CCINT,SCRext} and DBGVCR register entries in the cp14 array are missing their target register, resulting in all accesses being targetted at the guard sysreg (indexed by __INVALID_SYSREG__). Point the emulation code at the actual register entries.

device property: Don't clear secondary pointer for shared primary firmware node

2020-11-05T10:08:55Z

commit 99aed9227073fb34ce2880cbc7063e04185a65e1 upstream. It appears that firmware nodes can be shared between devices. In such case when a (child) device is about to be deleted, its firmware node may be shared and ACPI_COMPANION_SET(..., NULL) call for it breaks the secondary link of the shared primary firmware node. In order to prevent that, check, if the device has a parent and parent's firmware node is shared with its child, and avoid crashing the link.

device property: Keep secondary firmware node secondary by type

2020-11-05T10:08:55Z

commit d5dcce0c414fcbfe4c2037b66ac69ea5f9b3f75c upstream. Behind primary and secondary we understand the type of the nodes which might define their ordering. However, if primary node gone, we can't maintain the ordering by definition of the linked list. Thus, by ordering secondary node becomes first in the list. But in this case the meaning of it is still secondary (or auxiliary). The type of the node is maintained by the secondary pointer in it: secondary pointer Meaning NULL or valid primary node ERR_PTR(-ENODEV) secondary node So, if by some reason we do the following sequence of calls set_primary_fwnode(dev, NULL); set_primary_fwnode(dev, primary); we should preserve secondary node. This concept is supported by the description of set_primary_fwnode() along with implementation of set_secondary_fwnode(). Hence, fix the commit c15e1bdda436 to follow this as well.

ARM: s3c24xx: fix missing system reset

2020-11-05T10:08:55Z

commit f6d7cde84f6c5551586c8b9b68d70f8e6dc9a000 upstream. Commit f6361c6b3880 ("ARM: S3C24XX: remove separate restart code") removed usage of the watchdog reset platform code in favor of the Samsung SoC watchdog driver. However the latter was not selected thus S3C24xx platforms lost reset abilities.
