2023-01-07ARM: ux500: do not directly dereference __iomemJason A. Donenfeld1-6/+4
commit 65b0e307a1a9193571db12910f382f84195a3d29 upstream. Sparse reports that calling add_device_randomness() on `uid` is a violation of address spaces. And indeed the next usage uses readl() properly, but that was left out when passing it toadd_device_ randomness(). So instead copy the whole thing to the stack first.

[ Upstream commit 2254182807fc09ba9dec9a42ef239e373796f1b2 ] The DMA subsystem could be entirely disabled in Kconfig and then the TEGRA20_APB_DMA option isn't available too. Hence kernel configuration fails if DMADEVICES Kconfig option is disabled due to the unsatisfiable dependency. The FUSE driver isn't a critical driver and currently it only provides NVMEM interface to userspace which isn't known to be widely used, and thus, it's fine if FUSE driver fails to load. Let's remove the erroneous Kconfig dependency and let the FUSE driver to fail the probing if DMA is unavailable.

2022-09-08soc: sunxi: sram: Fix probe function ordering issuesSamuel Holland1-8/+5
Errors from debugfs are intended to be non-fatal, and should not prevent the driver from probing. Since debugfs file creation is treated as infallible, move it below the parts of the probe function that can fail. This prevents an error elsewhere in the probe function from causing the file to leak. Do the same for the call to of_platform_populate(). Finally, checkpatch suggests an octal literal for the file permissions.

git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/drivers Qualcomm driver updates for v5.20 This introduces a new driver that requests interconnect bandwidth based on throughput measurements of the bwmon hardware blocks found associated with, among other things, the CPU subsystem on many Qualcomm platforms. It introduces support for the SCM wrapper driver to vote for interconnect bandwidth for operations that needs bandwidth to the crypto engine. This ensures both performance and guards against issues caused by lacking votes for this path. The socinfo driver gains knowledge about the SC7180P SoC. It contains a range of fixes for spelling mistakes, refcount leaks in various drivers and removes some redundant code from the apr remove path. The SCM DT bindings are updated to declare support for QCS404, SM6125 and SDX65. The command db driver has a strncpy() converted to strscpy_pad() and then back again with proper documentation to why this was the right API. * tag 'qcom-drivers-for-5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: soc: qcom: icc-bwmon: Add bandwidth monitoring driver dt-bindings: interconnect: qcom,msm8998-cpu-bwmon: add BWMON device soc/qcom: Make QCOM_RPMPD select PM_GENERIC_DOMAINS/_OF soc: qcom: aoss: Fix refcount leak in qmp_cooling_devices_register soc: qcom: llcc: Fix syntax errors in comments soc: qcom: ocmem: Fix refcount leak in of_get_ocmem dt-bindings: soc: qcom,wcnss: remove unneeded ref for names firmware: qcom_scm: Add bw voting support to the SCM interface dt-bindings: firmware: qcom-scm: Add interconnects property soc: qcom: cmd-db: replace strscpy_pad() with strncpy() dt-bindings: firmware: scm: Add compatible for SDX65 dt-bindings: arm: qcom: switch maintainer to Bjorn soc: qcom: rpmhpd: fix typos in comment soc: qcom: correct kerneldoc soc: qcom: cmd-db: replace strncpy() with strscpy_pad() firmware: qcom_scm-legacy: correct kerneldoc dt-bindings: firmware: document Qualcomm QCS404 and SM6125 SCM soc: qcom: apr: Drop redundant check in .remove() firmware: qcom_scm: drop unexpected word "the" soc: qcom: socinfo: Add an ID for sc7180P Link: https://lore.kernel.org/r/20220712021830.1271398-1-bjorn.andersson@linaro.org Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2022-07-08soc: mediatek: mutex: Simplify with devm_platform_get_and_ioremap_resource()AngeloGioacchino Del Regno1-12/+6
Convert platform_get_resource(), devm_ioremap_resource() to a single call to devm_platform_get_and_ioremap_resource(), as this is exactly what this function does. While at it, also remove a redundant call to of_address_to_resource(), as this was getting the address of the same resource index 0: we can as well get the iostart from the 'regs' pointer.
