From 4181ef7dbb63e638739e929bca5b7bca3a37a311 Mon Sep 17 00:00:00 2001 From: Randy Dunlap Date: Mon, 30 Oct 2023 21:09:09 -0700 Subject: [PATCH] greybus: BeaglePlay driver needs CRC_CCITT The gb-beagleplay driver uses crc_ccitt(), so it should select CRC_CCITT to make sure that the function is available.
