irqchip/gic-v3-its: Silence warning when its_lpi_alloc_chunks gets inlined
More agressive inlining in recent versions of GCC have uncovered a new set of warnings: drivers/irqchip/irq-gic-v3-its.c: In function its_msi_prepare: drivers/irqchip/irq-gic-v3-its.c:1148:26: warning: lpi_base may be used uninitialized in this function [-Wmaybe-uninitialized] dev->event_map.lpi_base = lpi_base; ^ drivers/irqchip/irq-gic-v3-its.c:1116:6: note: lpi_base was declared here int lpi_base; ^ drivers/irqchip/irq-gic-v3-its.c:1149:25: warning: nr_lpis may be used uninitialized in this function [-Wmaybe-uninitialized] dev->event_map.nr_lpis = nr_lpis; ^ drivers/irqchip/irq-gic-v3-its.c:1117:6: note: nr_lpis was declared here int nr_lpis; ^ The warning is fairly benign (there is no code path that could actually use uninitialized variables), but let's silence it anyway by zeroing the variables on the error path.
