Subject: blktrace: kill the unneeded initcall
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=11a57153e3377ffdf8cfca2eda9a99063f66b957;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

blktrace: kill the unneeded initcall

It just inits the mutex, we can do that with DEFINE_MUTEX() instead.
