Martijn Coenen eb220f5318 ANDROID: binder: don't check prio permissions on restore. ... Because we have disabled RT priority inheritance for the regular binder domain, the following can happen: 1) thread A (prio 98) calls into thread B 2) because RT prio inheritance is disabled, thread B runs at the lowest nice (prio 100) instead 3) thread B calls back into A; A will run at prio 100 for the duration of the transaction 4) When thread A is done with the call from B, we will try to restore the prio back to 98. But, we fail because the process doesn't hold CAP_SYS_NICE, neither is RLIMIT_RT_PRIO set. While the proper fix going forward will be to correctly apply CAP_SYS_NICE or RLIMIT_RT_PRIO, for now it seems reasonable to not check permissions on the restore path.
