 漏洞归属组件：[kernel](https://gitee.com/src-openeuler/kernel)
 漏洞归属的版本：4.19.140,4.19.194,4.19.90,5.10.0,6.1.19,6.4.0,6.6.0
 CVSS V3.0分值：
  BaseScore：N/A None
  Vector：CVSS：3.0/
 漏洞简述：
  In the Linux kernel, the following vulnerability has been resolved:clk: imx95-blk-ctl: Fix synchronous abortWhen enabling runtime PM for clock suppliers that also belong to a powerdomain, the following crash is thrown:error: synchronous external abort: 0000000096000010 [#1] PREEMPT SMPWorkqueue: events_unbound deferred_probe_work_funcpstate: 60400009 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--)pc : clk_mux_get_parent+0x60/0x90lr : 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+0x70/0xd8Enabling runtime PM without explicitly resuming the device causedthe power domain cut off after clk_register() is called. As a result,a crash happens when the clock hardware provider is added and attemptsto 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.
