soc: fsl: qe: Check of ioremap return value

2022-03-08T18:14:14Z

[ Upstream commit a222fd8541394b36b13c89d1698d9530afd59a9c ] As the possible failure of the ioremap(), the par_io could be NULL. Therefore it should be better to check it and return error in order to guarantee the success of the initiation. But, I also notice that all the caller like mpc85xx_qe_par_io_init() in `arch/powerpc/platforms/85xx/common.c` don't check the return value of the par_io_init(). Actually, par_io_init() needs to check to handle the potential error. I will submit another patch to fix that. Anyway, par_io_init() itsely should be fixed.

soc: fsl: guts: Add a missing memory allocation failure check

2022-03-08T18:14:14Z

[ Upstream commit b9abe942cda43a1d46a0fd96efb54f1aa909f757 ] If 'devm_kstrdup()' fails, we should return -ENOMEM. While at it, move the 'of_node_put()' call in the error handling path and after the 'machine' has been copied. Better safe than sorry.

Pull ARM SoC driver updates from Arnd Bergmann: "These are all the driver updates for SoC specific drivers. There are a couple of subsystems with individual maintainers picking up their patches here: - The reset controller subsystem add support for a few new SoC variants to existing drivers, along with other minor improvements - The OP-TEE subsystem gets a driver for the ARM FF-A transport - The memory controller subsystem has improvements for Tegra, Mediatek, Renesas, Freescale and Broadcom specific drivers. - The tegra cpuidle driver changes get merged through this tree this time. There are only minor changes, but they depend on other tegra driver updates here. - The ep93xx platform finally moves to using the drivers/clk/ subsystem, moving the code out of arch/arm in the process. This depends on a small sound driver change that is included here as well. - There are some minor updates for Qualcomm and Tegra specific firmware drivers. The other driver updates are mainly for drivers/soc, which contains a mixture of vendor specific drivers that don't really fit elsewhere: - Mediatek drivers gain more support for MT8192, with new support for hw-mutex and mmsys routing, plus support for reset lines in the mmsys driver. - Qualcomm gains a new "sleep stats" driver, and support for the "Generic Packet Router" in the APR driver. - There is a new user interface for routing the UARTS on ASpeed BMCs, something that apparently nobody else has needed so far. - More drivers can now be built as loadable modules, in particular for Broadcom and Samsung platforms. - Lots of improvements to the TI sysc driver for better suspend/resume support" Finally, there are lots of minor cleanups and new device IDs for amlogic, renesas, tegra, qualcomm, mediateka, samsung, imx, layerscape, allwinner, broadcom, and omap" * tag 'drivers-5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (179 commits) optee: Fix spelling mistake "reclain" -> "reclaim" Revert "firmware: qcom: scm: Add support for MC boot address API" qcom: spm: allow compile-testing firmware: arm_ffa: Remove unused 'compat_version' variable soc: samsung: exynos-chipid: add exynosautov9 SoC support firmware: qcom: scm: Don't break compile test on non-ARM platforms soc: qcom: smp2p: Add of_node_put() before goto soc: qcom: apr: Add of_node_put() before return soc: qcom: qcom_stats: Fix client votes offset soc: qcom: rpmhpd: fix sm8350_mxc's peer domain dt-bindings: arm: cpus: Document qcom,msm8916-smp enable-method ARM: qcom: Add qcom,msm8916-smp enable-method identical to MSM8226 firmware: qcom: scm: Add support for MC boot address API soc: qcom: spm: Add 8916 SPM register data dt-bindings: soc: qcom: spm: Document qcom,msm8916-saw2-v3.0-cpu soc: qcom: socinfo: Add PM8150C and SMB2351 models firmware: qcom_scm: Fix error retval in __qcom_scm_is_call_available() soc: aspeed: Add UART routing support soc: fsl: dpio: rename the enqueue descriptor variable soc: fsl: dpio: use an explicit NULL instead of 0 ...

soc: fsl: dpio: rename the enqueue descriptor variable

2021-10-22T00:38:56Z

The struct qbman_eq_desc 'd' variable declaration is covering one of the function parameters. This has no functional impact since this function parameter was not used after the new declaration. Even so, rename the variable so that we make the code more readable.
