2021-04-16mtd: core: Constify buf in mtd_write_user_prot_reg()Tudor Ambarus
The write buffer comes from user and should be const. Constify write buffer in mtd core and across all _write_user_prot_reg() users. cfi_cmdset_{0001, 0002} and onenand_base will pay the cost of an explicit cast to discard the const qualifier since the beginning, since they are using an otp_op_t function prototype that is used for both reads and writes. mtd_dataflash and SPI NOR will benefit of the const buffer because they are using different paths for writes and reads.

.set_ios() is called from .resume() as well. For SDIO device which sets keep-power-in-suspend, nothing should be changed after resuming, as well as sample tuning value, since this value is tuned already. So we should not overwrite it with the default value.

2021-04-16spi: spi-zynqmp-gqspi: return -ENOMEM if dma_map_single failsQuanyang Wang
The spi controller supports 44-bit address space on AXI in DMA mode, so set dma_addr_t width to 44-bit to avoid using a swiotlb mapping. In addition, if dma_map_single fails, it should return immediately instead of continuing doing the DMA operation which bases on invalid address. This fixes the following crash which occurs in reading a big block from flash: [ 123.633577] zynqmp-qspi ff0f0000.spi: swiotlb buffer is full (sz: 4194304 bytes), total 32768 (slots), used 0 (slots) [ 123.644230] zynqmp-qspi ff0f0000.spi: ERR:rxdma:memory not mapped [ 123.784625] Unable to handle kernel paging request at virtual address 00000000003fffc0 [ 123.792536] Mem abort info: [ 123.795313] ESR = 0x96000145 [ 123.798351] EC = 0x25: DABT (current EL), IL = 32 bits [ 123.803655] SET = 0, FnV = 0 [ 123.806693] EA = 0, S1PTW = 0 [ 123.809818] Data abort info: [ 123.812683] ISV = 0, ISS = 0x00000145 [ 123.816503] CM = 1, WnR = 1 [ 123.819455] user pgtable: 4k pages, 48-bit VAs, pgdp=0000000805047000 [ 123.825887] [00000000003fffc0] pgd=0000000803b45003, p4d=0000000803b45003, pud=0000000000000000 [ 123.834586] Internal error: Oops: 96000145 [#1] PREEMPT SMP Fixes: 1c26372e5aa9 ("spi: spi-zynqmp-gqspi: Update driver to use spi-mem framework") Signed-off-by: Quanyang Wang <quanyang.wang@windriver.com> Link: https://lore.kernel.org/r/20210416004652.2975446-6-quanyang.wang@windriver.com Signed-off-by: Mark Brown <broonie@kernel.org>

2021-04-16spi: spi-zynqmp-gqspi: fix hang issue when suspend/resumeQuanyang Wang
After calling platform_set_drvdata(pdev, xqspi) in probe, the return value of dev_get_drvdata(dev) is a pointer to struct zynqmp_qspi but not struct spi_controller. A wrong structure type passing to the functions spi_controller_suspend/resume will hang the system. And we should check the return value of spi_controller_suspend, if an error is returned, return it to PM subsystem to stop suspend. Also, GQSPI_EN_MASK should be written to GQSPI_EN_OFST to enable the spi controller in zynqmp_qspi_resume since it was disabled in zynqmp_qspi_suspend before.

2021-04-16spi: spi-zynqmp-gqspi: fix clk_enable/disable imbalance issueQuanyang Wang
The clks "pclk" and "ref_clk" are enabled twice during the probe. The first time is in the function zynqmp_qspi_probe and the second time is in zynqmp_qspi_setup_op which is called by devm_spi_register_controller. Then calling zynqmp_qspi_remove (rmmod this module) to disable these clks will trigger a warning as below: [ 309.124604] Unpreparing enabled qspi_ref [ 309.128641] WARNING: CPU: 1 PID: 537 at drivers/clk/clk.c:824 clk_core_unprepare+0x108/0x110 Since pm_runtime works now, clks can be enabled/disabled by calling zynqmp_runtime_suspend/resume. So we don't need to enable these clks explicitly in zynqmp_qspi_setup_op. Remove them to fix this issue. And remove clk enabling/disabling in zynqmp_qspi_resume because there is no spi transfer operation so enabling ref_clk is redundant meanwhile pclk is not disabled for it is shared with other peripherals. Furthermore replace clk_enable/disable with clk_prepare_enable and clk_disable_unprepare in runtime_suspend/resume functions.

2021-04-16crypto: qat - enable detection of accelerators hangWojciech Ziemba
Enable the detection of hangs by setting watchdog timers (WDTs) on generations that supports that feature. The default timeout value comes from HW specs. WTDs are reset each time an accelerator wins arbitration and is able to send/read a command to/from an accelerator. The value has added significant margin to make sure there are no spurious timeouts. The scope of watchdog is per QAT device. If a timeout is detected, the firmware resets the accelerator and returns a response descriptor with an appropriate error code.

2021-04-16phy: phy-twl4030-usb: Fix possible use-after-free in twl4030_usb_remove()Yang Yingliang
This driver's remove path calls cancel_delayed_work(). However, that function does not wait until the work function finishes. This means that the callback function may still be running after the driver's remove function has finished, which would result in a use-after-free. Fix by calling cancel_delayed_work_sync(), which ensures that the work is properly cancelled, no longer running, and unable to re-schedule itself.

2021-04-16stm class: Use correct UUID APIsAndy Shevchenko
It appears that the STM code didn't manage to accurately decypher the delicate inner workings of an alternative thought process behind the UUID API and directly called generate_random_uuid() that clearly needs to be a static function in lib/uuid.c. At the same time, said STM code is poking directly at the byte array inside the uuid_t when it uses the UUID for its internal purposes. Fix these two transgressions by using intended APIs instead.
