misc: xilinx-sdfec: remove check for ioctl cmd and argument.
if (_IOC_TYPE(cmd) != PP_IOCTL)
return -ENOTTY;
Invalid ioctl command check normally performs by “default” case.
if (_IOC_DIR(cmd) != _IOC_NONE) {
argp = (void __user *)arg;
if (!argp)
return -EINVAL; }
And for checking ioctl arguments, copy_from_user()/copy_to_user()
checks are enough.
