[PATCH] rtc-dev.c: remove to_rtc_device macro

["Conke Hu" <conke.hu@gmail.com>]

hi,
  According to rtc_dev_open() in file rtc-dev.c (see below), all the
to_rtc_device macro in rtc file_operations functions should be
removed, namely:
  "struct rtc_device *rtc = to_rtc_device(file->private_data);"
should be modified to: "struct rtc_device *rtc = file->private_data;"

  to_rtc_device is not a correct usage here, what's more, pls consider
when dev were not the first member of struct rtc_device :)

static int rtc_dev_open(struct inode *inode, struct file *file)
{
    int err;
    //...<snip>

    file->private_data = rtc;

    //...<snip>
}
