memory: mtk-smi: fix device leak on larb probe

2026-03-04T12:21:00+00:00

[ Upstream commit 9dae65913b32d05dbc8ff4b8a6bf04a0e49a8eb6 ] Make sure to drop the reference taken when looking up the SMI device during larb probe on late probe failure (e.g. probe deferral) and on driver unbind.

Pull SoC driver updates from Arnd Bergmann: "This is the first half of the driver changes: - A treewide interface change to the "syscore" operations for power management, as a preparation for future Tegra specific changes - Reset controller updates with added drivers for LAN969x, eic770 and RZ/G3S SoCs - Protection of system controller registers on Renesas and Google SoCs, to prevent trivially triggering a system crash from e.g. debugfs access - soc_device identification updates on Nvidia, Exynos and Mediatek - debugfs support in the ST STM32 firewall driver - Minor updates for SoC drivers on AMD/Xilinx, Renesas, Allwinner, TI - Cleanups for memory controller support on Nvidia and Renesas" * tag 'soc-drivers-6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (114 commits) memory: tegra186-emc: Fix missing put_bpmp Documentation: reset: Remove reset_controller_add_lookup() reset: fix BIT macro reference reset: rzg2l-usbphy-ctrl: Fix a NULL vs IS_ERR() bug in probe reset: th1520: Support reset controllers in more subsystems reset: th1520: Prepare for supporting multiple controllers dt-bindings: reset: thead,th1520-reset: Add controllers for more subsys dt-bindings: reset: thead,th1520-reset: Remove non-VO-subsystem resets reset: remove legacy reset lookup code clk: davinci: psc: drop unused reset lookup reset: rzg2l-usbphy-ctrl: Add support for RZ/G3S SoC reset: rzg2l-usbphy-ctrl: Add support for USB PWRRDY dt-bindings: reset: renesas,rzg2l-usbphy-ctrl: Document RZ/G3S support reset: eswin: Add eic7700 reset driver dt-bindings: reset: eswin: Documentation for eic7700 SoC reset: sparx5: add LAN969x support dt-bindings: reset: microchip: Add LAN969x support soc: rockchip: grf: Add select correct PWM implementation on RK3368 soc/tegra: pmc: Add USB wake events for Tegra234 amba: tegra-ahb: Fix device leak on SMMU enable ...

memory: tegra186-emc: Fix missing put_bpmp

2025-11-22T12:41:24+00:00

Commit a52ddb98a674 ("memory: tegra186-emc: Simplify and handle deferred probe with dev_err_probe()") accidently dropped a call to 'put_bpmp' to release a handle to the BPMP when getting the EMC clock fails. Fix this by restoring the 'goto put_bpmp' if devm_clk_get() fails.

memory: tegra30-emc: Add the SoC model prefix to functions

2025-10-13T00:23:03+00:00

Replace "tegra_emc" with "tegra30_emc" in all functions to: 1. Avoid name clashing with other Tegra EMC drivers which makes it easier to jump to function definitions, 2. Decode the calltraces a bit easier, 3. Unify with other Tegra MC and EMC drivers, which use the SoC model prefixes. No functional impact. Reviewed-by: Jon Hunter Signed-off-by: Krzysztof Kozlowski
