2020-03-12libertas: Use new structure for SPI transfer delaysSergiu Cuciurean
In a recent change to the SPI subsystem [1], a new `delay` struct was added to replace the `delay_usecs`. This change replaces the current `delay_usecs` with `delay` for this driver. The `spi_transfer_delay_exec()` function [in the SPI framework] makes sure that both `delay_usecs` & `delay` are used (in this order to preserve backwards compatibility).

2020-03-12mwifiex: set needed_headroom, not hard_header_lenBrian Norris
hard_header_len provides limitations for things like AF_PACKET, such that we don't allow transmitting packets smaller than this. needed_headroom provides a suggested minimum headroom for SKBs, so that we can trivally add our headers to the front. The latter is the correct field to use in this case, while the former mostly just prevents sending small AF_PACKET frames. In any case, mwifiex already does its own bounce buffering [1] if we don't have enough headroom, so hints (not hard limits) are all that are needed. This is the essentially the same bug (and fix) that brcmfmac had, fixed in commit cb39288fd6bb ("brcmfmac: use ndev->needed_headroom to reserve additional header space").

2020-03-12qtnfmac: assign each wiphy to its own virtual platform deviceSergey Matyukevich
Quantenna Pearl device exposes multiple (up to 3) radio interfaces under single PCIe function. So far all the wiphy devices were attached to the same pcie device. As a result, all different wireless network devices were reported under the same sysfs directory for pcie device, e.g.: $ ls /sys/class/net/wlan0/device/net/ wlan0 wlan1 It turns out that such behavior may confuse various users of wireless subsystem. For instance, it turned out to be the case for: - Linux init systems, e.g. for renaming based on parent device - OpenWRT configuration scripts Suggested solution is to add an intermediate virtual platform device for each radio interface.

2020-03-12s390/dasd: fix data corruption for thin provisioned devicesStefan Haberland
Devices are formatted in multiple of tracks. For an Extent Space Efficient (ESE) volume we get errors when accessing unformatted tracks. In this case the driver either formats the track on the flight for write requests or returns zero data for read requests. In case a request spans multiple tracks, the indication of an unformatted track presented for the first track is incorrectly applied to all tracks covered by the request. As a result, tracks containing data will be handled as empty, resulting in zero data being returned on read, or overwriting existing data with zero on write. Fix by determining the track that gets the NRF error. For write requests only format the track that is surely not formatted. For Read requests all tracks before have returned valid data and should not be touched. All tracks after the unformatted track might be formatted or not. Those are returned to the blocklayer to build a new request. When using alias devices there is a chance that multiple write requests trigger a format of the same track which might lead to data loss. Ensure that a track is formatted only once by maintaining a list of currently processed tracks.

2020-03-12mmc: core: Respect MMC_CAP_NEED_RSP_BUSY for eMMC sleep commandUlf Hansson
The busy timeout for the CMD5 to put the eMMC into sleep state, is specific to the card. Potentially the timeout may exceed the host->max_busy_timeout. If that becomes the case, mmc_sleep() converts from using an R1B response to an R1 response, as to prevent the host from doing HW busy detection. However, it has turned out that some hosts requires an R1B response no matter what, so let's respect that via checking MMC_CAP_NEED_RSP_BUSY. Note that, if the R1B gets enforced, the host becomes fully responsible of managing the needed busy timeout, in one way or the other.

2020-03-12crypto: ccp - use file mode for sev ioctl permissionsConnor Kuehl
Instead of using CAP_SYS_ADMIN which is restricted to the root user, check the file mode for write permissions before executing commands that can affect the platform. This allows for more fine-grained access control to the SEV ioctl interface. This would allow a SEV-only user or group the ability to administer the platform without requiring them to be root or granting them overly powerful permissions. For example: chown root:root /dev/sev chmod 600 /dev/sev setfacl -m g:sev:r /dev/sev setfacl -m g:sev-admin:rw /dev/sev In this instance, members of the "sev-admin" group have the ability to perform all ioctl calls (including the ones that modify platform state). Members of the "sev" group only have access to the ioctls that do not modify the platform state. This also makes opening "/dev/sev" more consistent with how file descriptors are usually handled. By only checking for CAP_SYS_ADMIN, the file descriptor could be opened read-only but could still execute ioctls that modify the platform state. This patch enforces that the file descriptor is opened with write privileges if it is going to be used to modify the platform state. This flexibility is completely opt-in, and if it is not desirable by the administrator then they do not need to give anyone else access to /dev/sev.

2020-03-12tty: serial: ifx6x60: Convert to GPIO descriptorsLinus Walleij
This driver for the Intel MID never seems to have been properly integrated upstream: the platform data in <linux/spi/ifx_modem.h> is not used anywhere in the kernel and haven't been since it was merged into the kernel in 2010. There might be out-of-tree users, so I don't want to delete the driver, but I will refactor it to use GPIO descriptors, which means that out-of-tree users will need to adapt. There are several examples in the kernel of how to provide the resources necessary for using GPIO descriptors to pass in the GPIO lines, for the MID platform in particular, it will suffice to inspect the code in files like: arch/x86/platform/intel-mid/device_libs/platform_bt.c This refactoring transfers all GPIOs in the driver, including a hard-coded "PMU reset" in the driver to use GPIO descriptors instead.
