If anyone has any objections, please let me know. ------------------ From: David Lechner commit 89944d88f8795c6c89b9514cb365998145511cd4 upstream. Fix incorrect value mask for register write. Register values are 8-bit, not 9. If this function was called with a value > 0xFF and an even addr, it would cause writing to the next register.
