Subject: [SPARC] envctrl: implement ->unlocked_ioctl and ->compat_ioctl
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1928f8e541245eae933f8c95b64b2bc3683f9661;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

[SPARC] envctrl: implement ->unlocked_ioctl and ->compat_ioctl

all the ioctls in the driver are 32bit compat clean and don't need BKL,
so we can switch it to ->unlocked_ioctl and ->compat_ioctl trivially.
