Subject: ANDROID: binder: init desired_prio.sched_policy before use it
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8ff8351e7b97502dc5176519ebf8bd5f5dd1602a;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

ANDROID: binder: init desired_prio.sched_policy before use it

In function binder_transaction_priority(), we access
desired_prio before initialzing it.

This patch fix this.
