Jithu Joseph 2545deba31 platform/x86/intel/ifs: release cpus_read_lock() ... Couple of error paths in do_core_test() was returning directly without doing a necessary cpus_read_unlock(). Following lockdep warning was observed when exercising these scenarios with PROVE_RAW_LOCK_NESTING enabled: [ 139.304775] ================================================ [ 139.311185] WARNING: lock held when returning to user space! [ 139.317593] 6.6.0-rc2ifs01+ #11 Tainted: G S W I [ 139.324499] ------------------------------------------------ [ 139.330908] bash/11476 is leaving the kernel with locks still held! [ 139.338000] 1 lock held by bash/11476: [ 139.342262] #0: ffffffffaa26c930 (cpu_hotplug_lock){++++}-{0:0}, at: do_core_test+0x35/0x1c0 [intel_ifs] Fix the flow so that all scenarios release the lock prior to returning from the function.
