memory: mvebu-devbus: Fix missing clk_disable_unprepare in mvebu_devbus_probe()

2023-02-06T06:52:34+00:00

[ Upstream commit cb8fd6f75775165390ededea8799b60d93d9fe3e ] The clk_disable_unprepare() should be called in the error handling of devbus_get_timing_params() and of_platform_populate(), fix it by replacing devm_clk_get and clk_prepare_enable by devm_clk_get_enabled.

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

2022-10-26T11:22:31+00:00

[ Upstream commit 05215fb32010d4afb68fbdbb4d237df6e2d4567b ] 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()

2022-10-26T11:22:31+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.

[ Upstream commit 6f296a9665ba5ac68937bf11f96214eb9de81baa ] The device_node pointer is returned by of_parse_phandle() with refcount incremented. We should use of_node_put() on it when done.

memory: fsl_ifc: fix leak of irq and nand_irq in fsl_ifc_ctrl_probe

2021-11-17T08:48:42+00:00

[ Upstream commit 4ed2f3545c2e5acfbccd7f85fea5b1a82e9862d7 ] The error handling code of fsl_ifc_ctrl_probe is problematic. When fsl_ifc_ctrl_init fails or request_irq of fsl_ifc_ctrl_dev->irq fails, it forgets to free the irq and nand_irq. Meanwhile, if request_irq of fsl_ifc_ctrl_dev->nand_irq fails, it will still free nand_irq even if the request_irq is not successful. Fix this by refactoring the error handling code.
