CVE-2021-46934

In the Linux kernel, the following vulnerability has been resolved: i2c: validate user data in compat ioctl Wrong user data may cause warning in i2c_transfer(), ex: zero msgs. Userspace should not be able to trigger warnings, so this patch adds validation checks for user data in compact ioctl to prevent reported warnings
