Subject: [PATCH net-next v3 16/18] ps3_gelic: Replace usage of found with dedicated list iterator variable Date: Tue, 12 Apr 2022 14:15:55 +0200 Message-Id: <20220412121557.3553555-17-jakobkoschel@gmail.com> X-Mailer: git-send-email 2.25.1 In-Reply-To: <20220412121557.3553555-1-jakobkoschel@gmail.com> References: <20220412121557.3553555-1-jakobkoschel@gmail.com> MIME-Version: 1.0 Precedence: bulk List-ID: X-Mailing-List: bpf@vger.kernel.org X-Patchwork-Delegate: kuba@kernel.org 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.
