In the Linux kernel, the following vulnerability has been resolved: clk: imx95-blk-ctl: Fix synchronous abort When enabling runtime PM for clock suppliers that also belong to a power domain, the following crash is thrown: error: synchronous external abort: 0000000096000010 [#1] PREEMPT SMP Workqueue: events_unbound deferred_probe_work_func pstate: 60400009 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : clk_mux_get_parent+0x60/0x90 lr : clk_core_reparent_orphans_nolock+0x58/0xd8 Call trace: clk_mux_get_parent+0x60/0x90 clk_core_reparent_orphans_nolock+0x58/0xd8 of_clk_add_hw_provider.part.0+0x90/0x100 of_clk_add_hw_provider+0x1c/0x38 imx95_bc_probe+0x2e0/0x3f0 platform_probe+0x70/0xd8 Enabling runtime PM without explicitly resuming the device caused the power domain cut off after clk_register() is called. As a result, a crash happens when the clock hardware provider is added and attempts to access the BLK_CTL register. Fix this by using devm_pm_runtime_enable() instead of pm_runtime_enable() and getting rid of the pm_runtime_disable() in the cleanup path.
