Can a wording approach (like the following) become a part of a better change description?

  Direct memory access can not be properly performed any more
  after a dma_set_mask() call failed.

How do you think about to avoid a repeated reference to a function name?

How can this happen after you did not store the return value (in the local variable “error”)
for further usage (according to your proposed source code adjustment)?

I find it interesting that another personal name is presented here.
I noticed that some patches were published with the name “Ma Ke” previously.

How do you think about to use a summary phrase like “Complete error handling
in megaraid_probe_one()”?
