This is a note to let you know that I've just added the patch titled enetc: Fix unused var build warning for CONFIG_OF to the 5.10-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: enetc-fix-unused-var-build-warning-for-config_of.patch and it can be found in the queue-5.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 46e5105d05a088a29ea70d9ecb80904fdb711c4b Author: Arnd Bergmann <arnd@xxxxxxxx> Date: Fri Dec 4 14:08:00 2020 +0200 enetc: Fix unused var build warning for CONFIG_OF [ Upstream commit 4560b2a3ecdd5d587c4c6eea4339899f173a559a ] When CONFIG_OF is disabled, there is a harmless warning about an unused variable: enetc_pf.c: In function 'enetc_phylink_create': enetc_pf.c:981:17: error: unused variable 'dev' [-Werror=unused-variable] Slightly rearrange the code to pass around the of_node as a function argument, which avoids the problem without hurting readability.
