2017-04-14	rtc: cmos: Do not assume irq 8 for rtc when there are no legacy irqs	Hans de Goede	1	-4/+13
	On some systems (e.g. Intel Bay Trail systems) the legacy PIC is not used, in this case virq 8 will be a random irq, rather then hw_irq 8 from the PIC. Requesting virq 8 in this case will not help us to get alarm irqs and may cause problems for other drivers which actually do need virq 8, for example on an Asus Transformer T100TA this leads to: [ 28.745155] genirq: Flags mismatch irq 8. 00000088 (mmc0) vs. 00000080 (rtc0) <snip oops> [ 28.753700] mmc0: Failed to request IRQ 8: -16 [ 28.975934] sdhci-acpi: probe of 80860F14:01 failed with error -16 This commit fixes this by making the rtc-cmos driver continue without using an irq rather then claiming irq 8 when no irq is specified in the pnp-info and there are no legacy-irqs.

2017-04-14	x86: i8259: export legacy_pic symbol	Hans de Goede	1	-0/+1
	The classic PC rtc-coms driver has a workaround for broken ACPI device nodes for it which lack an irq resource. This workaround used to unconditionally hardcode the irq to 8 in these cases. This was causing irq conflict problems on systems without a legacy-pic so a recent patch added an if (nr_legacy_irqs()) guard to the workaround to avoid this irq conflict. nr_legacy_irqs() uses the legacy_pic symbol under the hood causing an undefined symbol error if the rtc-cmos code is build as a module. This commit exports the legacy_pic symbol to fix this.
