Subject: mm/mmap: remove unnecessary assignment
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2d8a17813ec817fa58addd2c92b4ca8cae5bafbb;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

mm/mmap: remove unnecessary assignment

pgoff is not used after the statement "pgoff = vma->vm_pgoff;", so the
assignment is redundant.
