Hello!

The diff looks fine to me, but there are some minor issues with the
commit message.  This is how it ended up looking in for me with "git
log":

---
commit 5e3f386fdb23c8e5ba7c24ff5efd6beb73db3e85 (HEAD -> bugfix-master)

The issues I see there are:


 1) subject should have a prefix - e.g. "net: usb: qmi_wwan:"
 
 2) don't repeat the subject in the body - that's redundant and ends up
    looking like a duplicate line in the commit message.  Write
    something addding more information instead.  Anything you find
    relevant
 

 3) I guess you send from a gmail address for a reason.  But you most
    likely want the Author field to match your Signed-off-by?  You can fix
    this by including something like this as the *first* line of the
    message body:

       From: Ethan Yang <etyang@...rrawireless.com>



FYI: checkpatch warns about the last issue:

bjorn@...aculix:/usr/local/src/git/linux$ scripts/checkpatch.pl /tmp/xx
WARNING: From:/Signed-off-by: email address mismatch: 'From: Ethan Yang <ipis.yang@...il.com>' != 'Signed-off-by: Ethan Yang <etyang@...rrawireless.com>'

total: 0 errors, 1 warnings, 0 checks, 7 lines checked

NOTE: For some of the reported defects, checkpatch may be able to
      mechanically convert to the typical style using --fix or --fix-inplace.

/tmp/xx has style problems, please review.

NOTE: If any of the errors are false positives, please report
      them to the maintainer, see CHECKPATCH in MAINTAINERS.
