Subject: ARM i.MX6q: unmap memory mapped at imx6q_opp_check_speed_grading()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=23bec1727505de4adf3f0ed228bcb8b1a3d2e551;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ARM i.MX6q: unmap memory mapped at imx6q_opp_check_speed_grading()

imx6q_opp_check_speed_grading() remaps memory to the base variable and
never unmaps it. I can't see how this can be of any use later so here I
unmap it.
