Checkpatch issues "WARNING: else is not generally useful after a break
or return" for the following code:
while (1) {
do_join_r = rtw_do_join(padapter);
if (do_join_r == _SUCCESS) {
break;
} else {
rtw_dec_to_roam(padapter);
if (rtw_to_roam(padapter) > 0) {
continue;
} else {
rtw_indicate_disconnect(padapter);
break;
}
}
}
We simplify this code in multiple steps. First, we remove do_join_r
variable because it is only used right after it is assigned. Second,
we remove the unnecessary else statement right after break:
while (1) {
if (rtw_do_join(padapter) == _SUCCESS)
break;
rtw_dec_to_roam(padapter);
if (rtw_to_roam(padapter) > 0) {
continue;
} else {
rtw_indicate_disconnect(padapter);
break;
}
}
Next, we move the call to rtw_do_join into the while test because the
while will loop only until the call is successful:
while (rtw_do_join(padapter) != _SUCCESS) {
rtw_dec_to_roam(padapter);
if (rtw_to_roam(padapter) > 0) {
continue;
} else {
rtw_indicate_disconnect(padapter);
break;
}
}
Finally, looking at the code above, it is clear that the code will
break out of the loop if rtw_to_roam call is <= 0. Hence:
while (rtw_do_join(padapter) != _SUCCESS) {
rtw_dec_to_roam(padapter);
if (rtw_to_roam(padapter) <= 0) {
rtw_indicate_disconnect(padapter);
break;
}
}

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
