Fix this by replacing the use of pm_sleep_ptr() by a custom wrapper. Fixes: 727eb02eb753375e ("pinctrl: renesas: Switch to use DEFINE_NOIRQ_DEV_PM_OPS() helper") Signed-off-by: Geert Uytterhoeven --- To be queued in renesas-pinctrl for v6.9. Alternatively, one could add a unified definition: #define pm_psci_sleep_ptr(_ptr) PTR_IF(IS_ENABLED(CONFIG_PM_SLEEP) && \ IS_ENABLED(CONFIG_ARM_PSCI_FW), (_ptr)) Since there are already separate sections for CONFIG_ARM_PSCI_FW enabled vs. disabled, I split in two and simplified the definition. --- drivers/pinctrl/renesas/core.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/drivers/pinctrl/renesas/core.c b/drivers/pinctrl/renesas/core.c index 78331d7f7cca9d8c..96d6040a8871419b 100644 --- a/drivers/pinctrl/renesas/core.c +++ b/drivers/pinctrl/renesas/core.c @@ -737,10 +737,12 @@ static int sh_pfc_resume_noirq(struct device *dev) sh_pfc_walk_regs(pfc, sh_pfc_restore_reg); return 0; } +#define pm_psci_sleep_ptr(_ptr) pm_sleep_ptr(_ptr) #else static int sh_pfc_suspend_init(struct sh_pfc *pfc) { return 0; } static int sh_pfc_suspend_noirq(struct device *dev) { return 0; } static int sh_pfc_resume_noirq(struct device *dev) { return 0; } +#define pm_psci_sleep_ptr(_ptr) PTR_IF(false, (_ptr)) #endif /* CONFIG_ARM_PSCI_FW */ static DEFINE_NOIRQ_DEV_PM_OPS(sh_pfc_pm, sh_pfc_suspend_noirq, sh_pfc_resume_noirq); @@ -1423,7 +1425,7 @@ static struct platform_driver sh_pfc_driver = { .driver = { .name = DRV_NAME, .of_match_table = of_match_ptr(sh_pfc_of_table), - .pm = pm_sleep_ptr(&sh_pfc_pm), + .pm = pm_psci_sleep_ptr(&sh_pfc_pm), }, };
