2017-01-27block: simplify blk_init_allocated_queueChristoph Hellwig
Return an errno value instead of the passed in queue so that the callers don't have to keep track of two queues, and move the assignment of the request_fn and lock to the caller as passing them as argument doesn't simplify anything. While we're at it also remove two pointless NULL assignments, given that the request structure is zeroed on allocation.

2017-01-20xhci: remove WARN_ON if dma mask is not set for platform devicesMathias Nyman
The warn on is a bit too much, we will anyway set the dma mask if not set previously. The main reason for this fix is that 4.10-rc1 has a dwc3 change that pass a parent sysdev dev pointer instead of setting the dma mask of its xhci platform device. xhci platform driver can then get more attributes from the sysdev than just the dma mask. The usb core and xhci changes are not yet in 4.10, and a fix like this was preferred instead of taking those big changes this late in the rc-cycle.

2017-01-19HID: wacom: Fix sibling detection regressionJason Gerecke
Commit 345857b ("HID: wacom: generic: Add support for sensor offsets") included a change to the operation and location of the call to 'wacom_add_shared_data' in 'wacom_parse_and_register'. The modifications included moving it higher up so that it would occur before the call to 'wacom_retrieve_hid_descriptor'. This was done to prevent a crash that would have occured when the report containing tablet offsets was fed into the driver with 'wacom_hid_report_raw_event' (specifically: the various 'wacom_wac_*_report' functions were written with the assumption that they would only be called once tablet setup had completed; 'wacom_wac_pen_report' in particular dereferences 'shared' which wasn't yet allocated). Moving the call to 'wacom_add_shared_data' effectively prevented the crash but also broke the sibiling detection code which assumes that the HID descriptor has been read and the various device_type flags set. To fix this situation, we restore the original 'wacom_add_shared_data' operation and location and instead implement an alternative change that can also prevent the crash. Specifically, we notice that the report functions mentioned above expect to be called only for input reports. By adding a check, we can prevent feature reports (such as the offset report) from causing trouble.

mpt3sas has a firmware failure where it can only handle one pass through ATA command at a time. If another comes in, contrary to the SAT standard, it will hang until the first one completes (causing long commands like secure erase to timeout). The original fix was to block the device when an ATA command came in, but this caused a regression with commit 669f044170d8933c3d66d231b69ea97cb8447338 Author: Bart Van Assche <bart.vanassche@sandisk.com> Date: Tue Nov 22 16:17:13 2016 -0800 scsi: srp_transport: Move queuecommand() wait code to SCSI core So fix the original fix of the secure erase timeout by properly returning SAM_STAT_BUSY like the SAT recommends.

2017-01-17scsi: sd: Fix wrong DPOFUA disable in sd_read_cache_typeDamien Le Moal
Zoned block devices force the use of READ/WRITE(16) commands by setting sdkp->use_16_for_rw and clearing sdkp->use_10_for_rw. This result in DPOFUA always being disabled for these drives as the assumed use of the deprecated READ/WRITE(6) commands only looks at sdkp->use_10_for_rw. Strenghten the test by also checking that sdkp->use_16_for_rw is false. Signed-off-by: Damien Le Moal <damien.lemoal@wdc.com> Reviewed-by: Hannes Reinecke <hare@suse.com> Signed-off-by: Martin K.
