2021-06-14staging: qlge: change msleep to usleep_rangeTobias Alam1-1/+1
This patch changes msleep() to usleep_range() based on Documentation/timers/timers-howto.txt. It suggests using usleep_range() for small msec(1ms - 20ms) because msleep() will often sleep longer than the desired value. Issue found by checkpatch.

2021-06-14staging: rtl8188eu: convert DBG_88E calls in core/rtw_recv.cPhillip Potter1-17/+38
Convert all calls to the DBG_88E macro in core/rtw_recv.c into netdev_dbg calls. The DBG_88E macro is unnecessary, as visibility of debug messages can be controlled more precisely by just using debugfs. It is important to keep these messages still, as they are displayable via a kernel module parameter when using DBG_88E. One such converted call is after a failed skb allocation, but as it prints additional information besides just stating failure, I've left it in despite the checkpatch warning.

2021-06-14ata: ahci_sunxi: Disable DIPMTimo Sigurdsson1-1/+1
DIPM is unsupported or broken on sunxi. Trying to enable the power management policy med_power_with_dipm on an Allwinner A20 SoC based board leads to immediate I/O errors and the attached SATA disk disappears from the /dev filesystem. A reset (power cycle) is required to make the SATA controller or disk work again. The A10 and A20 SoC data sheets and manuals don't mention DIPM at all [1], so it's fair to assume that it's simply not supported. But even if it was, it should be considered broken and best be disabled in the ahci_sunxi driver.

2021-06-14HID: intel-ish-hid: ishtp: Add dma_no_cache_snooping() callbackEven Xu2-0/+19
Different platforms have different DMA capability, on most of platforms, DMA support cache snooping. But few platforms, such as ElkhartLake (EHL), don't support cache snooping which requires cache flush from driver. So add a hardware level callback to let ishtp driver know if cache flush is needed. As most of platform support cache snooping, so driver will not do cache flush by default, until platform implements this callback and return true explicitly.

This reverts commit 4c38f2df71c8e33c0b64865992d693f5022eeaad. There are few races in the frequency invariance support for CPPC driver, namely the driver doesn't stop the kthread_work and irq_work on policy exit during suspend/resume or CPU hotplug. A proper fix won't be possible for the 5.13-rc, as it requires a lot of changes. Lets revert the patch instead for now.

It has been reported that usage of memcpy() to/from an iomem mapping is invalid, and a recent arm64 memcpy update [1] triggers a memory abort when dram-access-quirk is used on the G12A/G12B platforms. This adds a local sg_copy_to_buffer which makes usage of io versions of memcpy when dram-access-quirk is enabled.

The card timing and the bus frequency are not changed atomically with respect to calls to the set_clock() callback in the driver. The result is the driver sees a transient state where there's a mismatch between the two and thus the inputs to the phase correction calculation formula are garbage. Switch from dev_warn() to dev_dbg() to avoid noise in the normal case, though the change does make bad configurations less likely to be noticed.

2021-06-14mmc: core: Allow UHS-I voltage switch for SDSC cards if supportedChristian Löhle1-4/+6
While initializing an UHS-I SD card, the mmc core first tries to switch to 1.8V I/O voltage, before it continues to change the settings for the bus speed mode. However, the current behaviour in the mmc core is inconsistent and doesn't conform to the SD spec. More precisely, an SD card that supports UHS-I must set both the SD_OCR_CCS bit and the SD_OCR_S18R bit in the OCR register response. When switching to 1.8V I/O the mmc core correctly checks both of the bits, but only the SD_OCR_S18R bit when changing the settings for bus speed mode. Rather than actually fixing the code to confirm to the SD spec, let's deliberately deviate from it by requiring only the SD_OCR_S18R bit for both parts. This enables us to support UHS-I for SDSC cards (outside spec), which is actually being supported by some existing SDSC cards. Moreover, this fixes the inconsistent behaviour.

This patch fixes the following issues: 1. memstick_free_host() will free the host, so the use of ms_dev(host) after it will be a problem. To fix this, move memstick_free_host() after when we are done with ms_dev(host). 2. In rtsx_usb_ms_drv_remove(), pm need to be disabled before we remove and free host otherwise memstick_check will be called and UAF will happen.
