Despite checkpatch, I think that the original code was easier to
understand.

It'd likely be easier to understand if all the
<foo>_valid uses were bool and the ql_get_both_serdes
<foo>_valid arguments were change to bool from
unsigned int as well.

btw: qlge likely is going to be deleted and not updated.

Indeed, given the names and the values, bool would be much better.

OK.  Jules, if you want to make this change, you can, but it could be
better to move on to some other driver.

thanks,

Re: [Outreachy kernel] [PATCH] staging: qlge: Fix multiple assignments warning by splitting the assignement into two each

[Dan Carpenter]

I was just about to give a newbie a Reviewed-by cookie until I saw it
was a Joe Perches patch without a commit message or a sign off.  And
then I was annoyed that I had invested any time in it at all.  I even
dropped out of my email client for this!

:P

If you want to resend as a proper commit then you can still have my
Reviewed-by I guess.

Reviewed-by: Dan Carpenter <dan.carpenter@oracle.com>

dan carpenter
