memory: of: Fix refcount leak bug in of_lpddr3_get_ddr_timings()

2022-10-24T07:57:24+00:00

[ Upstream commit 48af14fb0eaa63d9aa68f59fb0b205ec55a95636 ]

We should add the of_node_put() when breaking out of
for_each_child_of_node() as it will automatically increase
and decrease the refcount.

memory: pl353-smc: Fix refcount leak bug in pl353_smc_probe()

2022-10-24T07:57:24+00:00

[ Upstream commit 61b3c876c1cbdb1efd1f52a1f348580e6e14efb6 ]

The break of for_each_available_child_of_node() needs a
corresponding of_node_put() when the reference 'child' is not
used anymore. Here we do not need to call of_node_put() in
fail path as '!match' means no break.

While the of_platform_device_create() will created a new
reference by 'child' but it has considered the refcounting.

memory: samsung: exynos5422-dmc: Fix refcount leak in of_get_dram_timings

2022-06-06T09:18:20+00:00

of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
This function doesn't call of_node_put() in some error paths.
To unify the structure, Add put_node label and goto it on errors.

memory: omap-gpmc: OMAP_GPMC should depend on ARCH_OMAP2PLUS || ARCH_KEYSTONE || ARCH_K3

2022-06-06T09:10:53+00:00

The Texas Instruments OMAP General Purpose Memory Controller (GPMC) is
only present on TI OMAP2/3/4/5, Keystone, AM33xx, AM43x, DRA7xx, TI81xx,
and K3 SoCs.  Hence add a dependency on ARCH_OMAP2PLUS || ARCH_KEYSTONE
|| ARCH_K3, to prevent asking the user about this driver when
configuring a kernel without OMAP2+, Keystone, or K3 SoC family support.

Pull ARM driver updates from Arnd Bergmann:
 "There are minor updates to SoC specific drivers for chips by Rockchip,
  Samsung, NVIDIA, TI, NXP, i.MX, Qualcomm, and Broadcom.

  Noteworthy driver changes include:

   - Several conversions of DT bindings to yaml format.

   - Renesas adds driver support for R-Car V4H, RZ/V2M and RZ/G2UL SoCs.

   - Qualcomm adds a bus driver for the SSC (Snapdragon Sensor Core),
     and support for more chips in the RPMh power domains and the
     soc-id.

   - NXP has a new driver for the HDMI blk-ctrl on i.MX8MP.

   - Apple M1 gains support for the on-chip NVMe controller, making it
     possible to finally use the internal disks. This also includes SoC
     drivers for their RTKit IPC and for the SART DMA address filter.

  For other subsystems that merge their drivers through the SoC tree, we
  have

   - Firmware drivers for the ARM firmware stack including TEE, OP-TEE,
     SCMI and FF-A get a number of smaller updates and cleanups. OP-TEE
     now has a cache for firmware argument structures as an
     optimization, and SCMI now supports the 3.1 version of the
     specification.

   - Reset controller updates to Amlogic, ASpeed, Renesas and ACPI
     drivers

   - Memory controller updates for Tegra, and a few updates for other
     platforms"
