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.
