[PATCH] tee: optee: replace might_sleep with cond_resched

2020-09-18 Thread Rouven Czerwinski
On Kernels with CONFIG_PREEMPT_NONE might_sleep() is not enough to force rescheduling, replace it with a resched check and cond_resched. Fixes the following stall: [ 572.945146] rcu: INFO: rcu_sched self-detected stall on CPU [ 572.949275] rcu: 0-: (2099 ticks this GP) idle=572/1/0x4
