Shuicheng Lin 08fdfd260e drm/xe/hw_engine_group: Fix double write lock release in error path ... In xe_hw_engine_group_get_mode(), a write lock is acquired before calling switch_mode(), which in turn invokes xe_hw_engine_group_suspend_faulting_lr_jobs(). On failure inside xe_hw_engine_group_suspend_faulting_lr_jobs(), the write lock is released there, and then again in xe_hw_engine_group_get_mode(), leading to a double release. Fix this by keeping both acquire and release operation in xe_hw_engine_group_get_mode().
