[Qemu-devel] [PATCH v6 0/2] dump: let dump_error return error reason to caller

[zhanghailiang]

Hi,

In original code, Function dump_error ignores its second parameter which 
contains
error reason, it is better to return the error message to the caller.

Here we use error_setg to return the error info to caller.
And at the same time, we turn functions like write_elf64_note() to void,
Because functions shouldn't return an error code _and_ an Error object.
After this modification the code will be more clean. 

v5 -> v6
- Don't check *errp directly, if errp is NULL, there will be an error,
  Instead, check a local variable *local_err (Markus Armbruster) 
v4 -> v5:
- Turn functions like write_elf64_note() to void (Luiz Capitulino)
v3 -> v4:
- Adjust the errp argument to the end 
- Remove trailing '.' in error messages
v2 -> v3:
- Drop the '\n' in the message when call dump_error(Eric Blake) 
v1 -> v2:
- Return the error reason to the caller (Luiz Capitulino)
