Subject: staging: android/lowmemorykiller: No need for task->signal check
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=353416099128914a684e8bb81e7475d8c2961cc3;p=linux-beck.git

staging: android/lowmemorykiller: No need for task->signal check

task->signal == NULL is not possible, so no need for these checks.
