Title
pmdomain: arm: scmi: Fix genpd leak on provider registration failure
Summary
In the Linux kernel, the following vulnerability has been resolved: pmdomain: arm: scmi: Fix genpd leak on provider registration failure If of_genpd_add_provider_onecell() fails during probe, the previously created generic power domains are not removed, leading to a memory leak and potential kernel crash later in genpd_debug_add(). Add proper error handling to unwind the initialized domains before returning from probe to ensure all resources are correctly released on failure. Example crash trace observed without this fix: | Unable to handle kernel paging request at virtual address fffffffffffffc70 | CPU: 1 UID: 0 PID: 1 Comm: swapper/0 Not tainted 6.18.0-rc1 #405 PREEMPT | Hardware name: ARM LTD ARM Juno Development Platform/ARM Juno Development Platform | pstate: 00000005 (nzcv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--) | pc : genpd_debug_add+0x2c/0x160 | lr : genpd_debug_init+0x74/0x98 | Call trace: | genpd_debug_add+0x2c/0x160 (P) | genpd_debug_init+0x74/0x98 | do_one_initcall+0xd0/0x2d8 | do_initcall_level+0xa0/0x140 | do_initcalls+0x60/0xa8 | do_basic_setup+0x28/0x40 | kernel_init_freeable+0xe8/0x170 | kernel_init+0x2c/0x140 | ret_from_fork+0x10/0x20
