Subject: [PATCH net-next 07/15] qed: Replace usage of found with dedicated list iterator variable
Date: Thu, 7 Apr 2022 12:28:52 +0200 [thread overview]
Message-ID: <20220407102900.3086255-8-jakobkoschel@gmail.com> (raw)
In-Reply-To: <20220407102900.3086255-1-jakobkoschel@gmail.com>
To move the list iterator variable into the list_for_each_entry_*()
macro in the future it should be avoided to use the list iterator
variable after the loop body.
To *never* use the list iterator variable after the loop it was
concluded to use a separate iterator variable instead of a
found boolean [1].
This removes the need to use a found variable and simply checking if
the variable was set, can determine if the break/goto was hit.
