Summary
clk: imx95-blk-ctl: Fix synchronous abort
Details

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: eventsunbound deferredprobeworkfunc pstate: 60400009 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : clkmuxgetparent+0x60/0x90 lr : clkcorereparentorphansnolock+0x58/0xd8 Call trace: clkmuxgetparent+0x60/0x90 clkcorereparentorphansnolock+0x58/0xd8 ofclkaddhwprovider.part.0+0x90/0x100 ofclkaddhwprovider+0x1c/0x38 imx95bcprobe+0x2e0/0x3f0 platform_probe+0x70/0xd8

Enabling runtime PM without explicitly resuming the device caused the power domain cut off after clkregister() is called. As a result, a crash happens when the clock hardware provider is added and attempts to access the BLKCTL register.

Fix this by using devmpmruntimeenable() instead of pmruntimeenable() and getting rid of the pmruntime_disable() in the cleanup path.
