irqchip/gic: Correct declaration of *percpu_base pointer in union gic_base
[ Upstream commit a1855f1b7c33642c9f7a01991fb763342a312e9b ]
percpu_base is used in various percpu functions that expect variable in
__percpu address space. Correct the declaration of percpu_base to
void __iomem * __percpu *percpu_base;
to declare the variable as __percpu pointer.
The patch fixes several sparse warnings:
irq-gic.c:1172:44: warning: incorrect type in assignment (different address spaces)
irq-gic.c:1172:44: expected void [noderef] __percpu *[noderef] __iomem *percpu_base
irq-gic.c:1172:44: got void [noderef] __iomem *[noderef] __percpu *
...
irq-gic.c:1231:43: warning: incorrect type in argument 1 (different address spaces)
irq-gic.c:1231:43: expected void [noderef] __percpu *__pdata
irq-gic.c:1231:43: got void [noderef] __percpu *[noderef] __iomem *percpu_base
There were no changes in the resulting object files.
