From c6219deaee41bf35f7f04073f9ef99609d58bba4 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 17 Sep 2026 17:55:11 +0200 Subject: [PATCH] sfc: fix CONFIG_CXL_MEM dependency A recent patch introduced a call to devm_cxl_probe_mem(), which is only available when CXL_MEM is enabled. If CXL_MEM is in a loadable module, this causes a link failure for a builtin driver: s390-linux-ld: drivers/net/ethernet/sfc/efx_cxl.o: in function `efx_cxl_init': efx_cxl.c:(.text+0x156): undefined reference to `devm_cxl_probe_mem' Adapt the dependency to require CXL_MEM instead of CXL_BUS, which we know is available when CXL_MEM is.
