Pavankumar Kondeti 3054426dc6 sched, trace: Fix prev_state output in sched_switch tracepoint ... commit 3f5fe9fef5 ("sched/debug: Fix task state recording/printout") tried to fix the problem introduced by a previous commit efb40f588b ("sched/tracing: Fix trace_sched_switch task-state printing"). However the prev_state output in sched_switch is still broken. task_state_index() uses fls() which considers the LSB as 1. Left shifting 1 by this value gives an incorrect mapping to the task state. Fix this by decrementing the value returned by __get_task_state() before shifting.
