This says _what_ is happening here, but not _why_ this is needed at all.

Try taking a look a the kernel documentation for how to write a good
changelog text to make this much better.  It's often times the most
difficult portion of making a kernel patch, the code is easy, writing a
summary of why everyone else should agree that this code is acceptable
is hard.

good luck!
