This is indeed the case, ffc32cb0e1f6 pwm: Fix dependencies on HAS_IOMEM is supposed to fix this. > s390-linux-ld: drivers/pwm/pwm-brcmstb.o: in function `brcmstb_pwm_pro= be': > >> pwm-brcmstb.c:(.text+0x466): undefined reference to `devm_platform_ior= emap_resource' I expect that before the blamed commit (0e74dcd8333d ("pwm: brcmstb: Convert to devm_platform_ioremap_resource()")) the driver failed with: pwm-brcmstb.c:(.text+0xfoo): undefined reference to `devm_ioremap_resource' so it probably makes little sense to ensure the commit "pwm: Fix dependencies on HAS_IOMEM" comes before "pwm: brcmstb: Convert to devm_platform_ioremap_resource()" (and the other similar conversions). The only upside of rewriting the pwm-next tree would be that autobuilders wouldn't stumble because the error changed. Hardly good enough a reason, still more as the dependency is missing for quite some time already I guess.
