From 0e9e7598c68f1dc17ce1053b08494b8ed6dd4985 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 15 Oct 2021 23:06:01 +0200 Subject: octeontx2-nic: fix mixed module build Building the VF and PF side of this driver differently, with one being a loadable module and the other one built-in results in a link failure for the common PTP driver: ld.lld: error: undefined symbol: __this_module >>> referenced by otx2_ptp.c >>> net/ethernet/marvell/octeontx2/nic/otx2_ptp.o:(otx2_ptp_init) in archive drivers/built-in.a >>> referenced by otx2_ptp.c >>> net/ethernet/marvell/octeontx2/nic/otx2_ptp.o:(otx2_ptp_init) in archive drivers/built-in.a Move the otx2_ptp.c code into a separate module that gets built for both configurations, making it built-in if at least one of the other two is built-in.
