net: intel: igc_ptp: fix build for UML
[ Upstream commit 523994ba3ad1b7b55abe4a72e156897b5e2db825 ] On a UML build, the igc_ptp driver uses CONFIG_X86_TSC for timestamp conversion. The function that is used is not available on UML builds, so have the function use the default system_counterval_t timestamp instead for UML builds. Prevents this build error on UML: ../drivers/net/ethernet/intel/igc/igc_ptp.c: In function ‘igc_device_tstamp_to_system’: ../drivers/net/ethernet/intel/igc/igc_ptp.c:777:9: error: implicit declaration of function ‘convert_art_ns_to_tsc’ [-Werror=implicit-function-declaration] return convert_art_ns_to_tsc(tstamp); ../drivers/net/ethernet/intel/igc/igc_ptp.c:777:9: error: incompatible types when returning type ‘int’ but ‘struct system_counterval_t’ was expected return convert_art_ns_to_tsc(tstamp); Fixes: 68f5d3f3b654 ("um: add PCI over virtio emulation driver") Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Cc: linux-um@lists.infradead.org Cc: Jeff Dike <jdike@addtoit.com> Cc: Richard Weinberger <richard@nod.at> Cc: Anton Ivanov <anton.ivanov@cambridgegreys.com> Cc: Jesse Brandeburg <jesse.brandeburg@intel.com> Cc: Tony Nguyen <anthony.l.nguyen@intel.com> Cc: intel-wired-lan@lists.osuosl.org Link: https://lore.kernel.org/r/20211014050516.6846-1-rdunlap@infradead.org Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: Sasha Levin <sashal@kernel.org>
