If so, this change should be noted in the commit message.

Thanks for the catch! @Dimitry: Should I send an updated version or do you fix it yourself? regards;Richard.L

Some of the #defined register values are one-bit flags. Convert them to use the BIT(x) macro instead of 1 byte hexadecimal values. This improves readability and clarifies the intent.
