Summary
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.
