2021-02-09bus: fsl-mc: add the dpdbg device typeIoana Ciornei
A new object type was recently added in MC. This has to be added in the fsl-mc bus device type list so that it can be properly listed.

2021-02-09bus: fsl-mc: Fix test for end of loopDan Carpenter
The "desc" pointer can't possibly be NULL here. If we can't find the correct "desc" then tt points to the last element of the fsl_mc_accepted_cmds[] array. Fix this by testing if "i == FSL_MC_NUM_ACCEPTED_CMDS" instead.

2021-02-09HID: logitech-dj: add support for the new lightspeed connection iterationFilipe Laíns
This new connection type is the new iteration of the Lightspeed connection and will probably be used in some of the newer gaming devices. It is currently use in the G Pro X Superlight. This patch should be backported to older versions, as currently the driver will panic when seing the unsupported connection. This isn't an issue when using the receiver that came with the device, as Logitech has been using different PIDs when they change the connection type, but is an issue when using a generic receiver (well, generic Lightspeed receiver), which is the case of the one in the Powerplay mat. Currently, the only generic Ligthspeed receiver we support, and the only one that exists AFAIK, is ther Powerplay. As it stands, the driver will panic when seeing a G Pro X Superlight connected to the Powerplay receiver and won't send any input events to userspace! The kernel will warn about this so the issue should be easy to identify, but it is still very worrying how hard it will fail :( [915977.398471] logitech-djreceiver 0003:046D:C53A.0107: unusable device of type UNKNOWN (0x0f) connected on slot 1 Signed-off-by: Filipe Laíns <lains@riseup.net> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2021-02-09usb: dwc3: gadget: Fix dep->interval for fullspeed interruptThinh Nguyen
The dep->interval captures the number of frames/microframes per interval from bInterval. Fullspeed interrupt endpoint bInterval is the number of frames per interval and not 2^(bInterval - 1).

2021-02-09mei: bus: change remove callback to return voidUwe Kleine-König
The driver core ignores the return value of mei_cl_device_remove() so passing an error value doesn't solve any problem. As most mei drivers' remove callbacks return 0 unconditionally and returning a different value doesn't have any effect, change this prototype to return void and return 0 unconditionally in mei_cl_device_remove(). The only driver that could return an error value is modified to emit an explicit warning in the error case.

2021-02-09mei: bus: simplify mei_cl_device_remove()Uwe Kleine-König
The driver core only calls a bus' remove function when there is actually a driver and a device. So drop the needless check and assign cldrv earlier. (Side note: The check for cldev being non-NULL is broken anyhow, because to_mei_cl_device() is a wrapper around container_of() for a member that is not the first one. So cldev only can become NULL if dev is (void *)0xc (for archs with 32 bit pointers) or (void *)0x18 (for archs with 64 bit pointers).)

If MT8183 SoC support is enabled, almost all machines will use topckgen, apmixedsys, infracfg, mcucfg and subsystem clocks, so it feels wrong to require each one to select that symbols manually. Instead, enable it whenever COMMON_CLK_MT8183_* is disabled as a simplification. This would add few KB in the kernel image size but will make the life a bit easier to the users, anyway you'll need to probably enable all of them if you want to have proper support for that SoC.

In the wlan.h header, multiple structures contain a ieee80211_hdr member that is required to be two-byte aligned to avoid alignmnet faults when processing network headers, but all members are forced to be byte-aligned using the __packed tag at the end of the struct definition. In both cases, leaving out the packing does not change the internal layout of the structure but changes the alignment constraint of the structure itself.

2021-02-08scsi: iscsi: Drop session lock in iscsi_session_chkready()Mike Christie
The session lock in iscsi_session_chkready() is not needed because when we transition from logged into to another state we will block and/or remove the devices under the session, so no new I/O will be sent to the drivers after the block/remove. I/O that races with the block/removal is cleaned up by the drivers when it handles all outstanding I/O, so this just added an extra lock in the main I/O path. This patch removes the lock like other transport classes.

2021-02-08scsi: libiscsi: Reset max/exp cmdsn during recoveryMike Christie
If we lose the session then relogin, but the new cmdsn window has shrunk (due to something like an admin changing a setting) we will have the old exp/max_cmdsn values and will never be able to update them. For example, max_cmdsn would be 64, but if on the target the user set the window to be smaller then the target could try to return the max_cmdsn as 32. We will see that new max_cmdsn in the rsp but because it's lower than the old max_cmdsn when the window was larger we will not update it. So this patch has us reset the window values during session cleanup so they can be updated after a new login.

2021-02-08scsi: libiscsi: Fix iscsi_task use after free()Mike Christie
The following bug was reported and debugged by wubo40@huawei.com: When testing kernel 4.18 version, NULL pointer dereference problem occurs in iscsi_eh_cmd_timed_out() function. I think this bug in the upstream is still exists. The analysis reasons are as follows: 1) For some reason, I/O command did not complete within the timeout period. The block layer timer works, call scsi_times_out() to handle I/O timeout logic. At the same time the command just completes. 2) scsi_times_out() call iscsi_eh_cmd_timed_out() to process timeout logic. Although there is an NULL judgment for the task, the task has not been released yet now. 3) iscsi_complete_task() calls __iscsi_put_task(). The task reference count reaches zero, the conditions for free task is met, then iscsi_free_task() frees the task, and sets sc->SCp.ptr = NULL. After iscsi_eh_cmd_timed_out() passes the task judgment check, there can still be NULL dereference scenarios.

Note that this requires the previous patch, "scsi: libiscsi: Drop taskqueuelock" because bnx2i sleeps in its cleanup_task callout if the cmd is aborted. If the EH/timer and completion path are racing we don't know which path will do the last put. The previous patch moved the operations we needed to do under the forward lock to cleanup_queued_task. Once that has run we can drop the forward lock for the cmd and bnx2i no longer has to worry about if the EH, timer or completion path did the ast put and if the forward lock is held or not since it won't be.

2021-02-08scsi: libiscsi: Drop taskqueuelockMike Christie
The purpose of the taskqueuelock was to handle the issue where a bad target decides to send a R2T and before its data has been sent decides to send a cmd response to complete the cmd. The following patches fix up the frwd/back locks so they are taken from the queue/xmit (frwd) and completion (back) paths again. To get there this patch removes the taskqueuelock which for iSCSI xmit wq based drivers was taken in the queue, xmit and completion paths. Instead of the lock, we just make sure we have a ref to the task when we queue a R2T, and then we always remove the task from the requeue list in the xmit path or the forced cleanup paths.
