gpio-charger: Fix checking return value of request_any_context_irq
request_any_context_irq() returns a negative value on failure. On success, it returns either IRQC_IS_HARDIRQ or IRQC_IS_NESTED. Signed-off-by: Axel Lin <axel.lin@gmail.com> Acked-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Anton Vorontsov <cbouatmailru@gmail.com>
