When compile-testing without CONFIG_TI_SCI_PROTOCOL=m, there is a chance for a link failure, so add a careful dependency on that. arm-linux-gnueabi-ld: drivers/remoteproc/ti_k3_m4_remoteproc.o: in function `k3_m4_rproc_probe': ti_k3_m4_remoteproc.c:(.text.k3_m4_rproc_probe+0x76): undefined reference to `devm_ti_sci_get_by_phandle' Fixes: ebcf9008a895 ("remoteproc: k3-m4: Add a remoteproc driver for M4F subsystem") Signed-off-by: Arnd Bergmann <arnd@xxxxxxxx> --- drivers/mailbox/Kconfig | 2 +- drivers/mailbox/omap-mailbox.c | 2 +- drivers/remoteproc/Kconfig | 10 ++++------ 3 files changed, 6 insertions(+), 8 deletions(-) diff --git a/drivers/mailbox/Kconfig b/drivers/mailbox/Kconfig index 4eed97295927..ecaf78beb934 100644 --- a/drivers/mailbox/Kconfig +++ b/drivers/mailbox/Kconfig @@ -73,7 +73,7 @@ config ARMADA_37XX_RWTM_MBOXconfig OMAP2PLUS_MBOXtristate "OMAP2+ Mailbox framework support" - depends on ARCH_OMAP2PLUS || ARCH_K3 + depends on ARCH_OMAP2PLUS || ARCH_K3 || COMPILE_TEST help Mailbox implementation for OMAP family chips with hardware for interprocessor communication involving DSP, IVA1.0 and IVA2 in diff --git a/drivers/mailbox/omap-mailbox.c b/drivers/mailbox/omap-mailbox.c index 7a87424657a1..6797770474a5 100644 --- a/drivers/mailbox/omap-mailbox.c +++ b/drivers/mailbox/omap-mailbox.c @@ -603,7 +603,7 @@ static struct platform_driver omap_mbox_driver = { .driver = { .name = "omap-mailbox", .pm = &omap_mbox_pm_ops, - .of_match_table = of_match_ptr(omap_mailbox_of_match), + .of_match_table = omap_mailbox_of_match,
We could have done this in its own series. Someday we need to check everywhere for of_match being unconditionally defined but still using of_match_ptr(). Coccinelle might help here.. Anyway, LGTM Reviewed-by: Andrew Davis <afd@xxxxxx>
