By slight reorganisation we can avoid an else branch and some code
duplication which makes it easier to follow the code.

Is there any particular reason why you would want to avoid the else branch? I don't feel this patch is an improvement since by always setting cmdline_base to a non-zero value, as a reviewer I then have to check all other uses of cmdline_base in the file to ensure that this doesn't cause any issues.

I much prefer the existing version since setting the values of cmdline_base and initrd_base is very clearly scoped within the if statement.


ATB,

Mark.
